Research track record
- Reaserch projects:
In Progess:
- Silicon nanowire biosensors for healthcare and environmental control: My current research is funded by CRT, EWU. The overall aim of this project is to perform a detail investigation of different types of silicon nanowire (SiNW) biosensors with the target to solve one of the key outstanding issues which is the determination of the required thickness, length, surface states and appropriate bias voltages of different types of nanowires for single moleculer level detection. Single crystal and polycrystalline silicon nanowires will be realized and the complicated relationship of nanowires’ electrical behavior with parameters like nanowire length, thickness, doping, bias polarity, interface states will be investigated using the industry standard Technology Computer Aided Design tool Silvaco. This project builds up a unique platform of international collaboration between CRT, EWU and Southampton Nanofabrication Center, UK which is known as one of the topmost nanofabrication facilities in Europe. The project will have unique access to experimental samples from Southampton Nanofabrication Center, University of Southampton, UK allowing calibration, physical explanation thereby would provide the necessary insight into the required parameters for the desired electrical characteristics, process condition for realizing nanowires of appropriate materials and applicable bias conditions so that nanowire biosensor designs are optimized.
Completed:
- Silicon nanowire arrays for viral infection markers: My most recent research project is an UK Grand Challenge Project for Healthcare engineering using heterogeneous integration of silicon nanowires & bio-nanotechnology which was honoured with £1.3 Million by Engineering & Physical Sciences Research Council (EPSRC), UK. This is a multidisciplinary research project in which I was a Researcher Co-investigator, Peter Ashburn as Principal Investigator and co-investigators were from the School of Medicine, Chemistry, Sociology and Electronics of the University of Southampton. The aim of this research is to develop silicon nanowire biosensors with cost-effective electronic detection, into a robust user platform for large-scale biomarker diagnostics for a personalized, proactive and preventative healthcare. I have successfully developed a generic top-down fabrication approach for polysilicon nanowire fabricatio. The polysilicon is deposited by PECVD and a special anisotropic dry etch process is used to create rectangular nanowires. The whole process does not require any expensive lithography which just uses mature microelectronics (linewidths of >3mm) and thin film technology, offering a very low cost technology. A successful integration of functional biological molecules is achieved on these nanowires and the quantification of the immobilized biological complexes is done upon application of electric field which demonstrated a commercial route for nanowire biosensor fabrication. This has created an exciting opportunity for research on low cost diagnostic platform through a second phase of grant from TSB, UK. I have actively participated on this follow up proposal preparation.
- Nanowires using novel materials for smart biosensors, aerospace and defence companies and photonic applications:I have also participated on a collaborative research on realising nanowires using novel materials with Prof. Peter Ashburn and Dr. Chong in Southampton which has been awarded with £360, 000 from Oxford Instrument Plasma Technology (OIPT). As a starting, remote plasma atomic layer deposition (ALD) was used to successfully grow ZnO layer with a resistivity of 1 kΩ.cm and an estimated carrier concentration of ~ 6×1019cm-3. We have extensively studied the stoichiometry of our grown ZnO layer and the quality of the layer was assessed by fabrication of staggered bottom gate thin film transistors (TFT). Recently we have successfully fabricated rectangular ZnO nanowires using my generic generic top-down fabrication approach of deposition and etch in mature microelectronics (linewidths of >3mm). Currently we are investigating the ZnO nanowires developed by the aforementioned technology and a follow up proposal is also prepared which aims to realize stable p-type ZnO layer and junction less ZnO nanowire transistors. This research has several promises for exploitation. On one side ZnO nanowires are attractive for realising smart gas sensors for healthcare & environmental control, on the other hand this research will lead to a paradigm shift in wide bandgap semiconductor devices and lead to new fields of research into zinc oxide pn diodes, photonic devices, MOSFETs, MESFETs, bipolar transistors and power devices with obvious applications in aerospace/defence companies and display companies for transparent electronics.
- Silicon based nano CMOS devices: I also worked on a Engineering & Physical Sciences (EPSRC), UK funded research project (£648,248) aimed at investigating non-classical vertical MOSFETs for a viable route for improving the RF performance of mature CMOS technologies which exploits the lithography independent short channel definition technique of vertical MOSFETs. Several innovations came out of this research solving the problems of overlap capacitance, short channel effects and source/drain series resistances in these devices. We are the first group to realize a silicidation technology for surround gate vertical MOSFETs which was successfully integrated with a Fillet Local Oxidation (FILOX) process. In this way, a world record fT of 20 GHz was achieved for Si based nMOS devices for 0.5µm lithography offering a low cost route for improving the RF performance of mature lateral CMOS These inventions have attracted attention of several semiconductor industries.
- Engineering of smart nano-materials: My PhD research was a project of SINANO which aimed to strengthen European scientific and technological excellence in the field of Si-based nanodevices. This research focused on thin layer of amorphous silicon deposition and engineering its morphology by crystallization for transistor-in-grain technology and/or large area electronics. Two novel methods of low temperature crystallization of amorphous silicon were developed during this research. One method used fluorine during metal induced lateral crystallization (MILC) of amorphous silicon which delivered dramatically increased lateral crystallization distance (65%) and a high quality silicon layer. I also identified a new amorphous silicon crystallization phenomenon which originated from the perimeter of the germanium layer during low temperature anneal and excellent grain localization was achieved without any metal contamination. The developed methods of devising poly-silicon have a considerable commercial potential for some other applications like thin film solar cells, mass production of high quality silicon nanowires for bio-sensors & obviously for post scaling of CMOS using 3D integration.
- Simulation & compact model development: I also got an extensive experience of process/device simulation using SILVACO & SYNOPSIS TCAD tools and Matlab, C++ environment through several simulations which I undertook in the past. Simulation of vertical MOSFETs to study the device behaviour during transition from partial to fully depleted operation in vertical MOSFETs and simulation of PIN diode for a proposed novel multiplexed near field Terahertz microscope were carried out. A theoretical study on the quantum phenomena in deep sub micron MOSFETs with high-K dielectrics was also done. This Quantum mechanical modelling of MOS devices with high-K dielectrics was one of the earliest theoretical investigations of this type of structures.
