Here are a few interesting projects I have worked on over the years...
A lot of them were done as part of projects or reports required for classes I have taken.
Vijay MEMS Final Paper.pdfMEMS Fabrication
MEMS Fabrication
Final paper written at the end of a MEMS Fabrication course where I designed, fabricated and tested a thermally-actuated 2-D micromirror.
Fall 2018
Fabrication of AlGaN_GaN High Electron Mobility Transistors.pdfUndergraduate Senior Design Project : Fabrication of AlGaN/GaN High Electron Mobility Transistors
Undergraduate Senior Design Project : Fabrication of AlGaN/GaN High Electron Mobility Transistors
A first fabrication attempt of an AlGaN/GaN HEMT on Si substrate at RIT.
I came up with a relatively simple process flow and went through a first run of fabrication over the course of my senior year towards an enhancement-mode device.

QuantumFinalProject_Ver3.pdfWell Shapes and Derivation of Energy Levels
Well Shapes and Derivation of Energy Levels
Final paper with associated MATLAB code written for Physics of Nanostructures course. Feel free to use the code to calculate energy levels for different quantum well shapes and conditions! Well shapes include square, linear-triangular, v-shaped triangular, full harmonic and half-harmonic oscillators.

FinalPaper_SiGeVijay_Spring2019.pdfReview of Ohmic Contacts to GaN and AlGaN
Review of Ohmic Contacts to GaN and AlGaN
A quick term paper to summarize the results a few papers showed in regards to Ohmic contacts to GaN. This was a summary of a few papers compiled together and written for a SiGe and SOI Devices course. The main goal in me writing this paper was to delve deeper and provide ideas and an increased understanding towards better HEMT devices based off of results I had originally obtained for Senior Design.

FinalPaper_Vijay_V1.pdfSummarizing record multi-junction solar cells
Summarizing record multi-junction solar cells
A final term paper summarizing the design, crystal growth, fabrication and performance metrics of the highest efficiency multi-junction solar cell reported in literature to-date at the time of writing.
Spring 2022
ImplantProject_Vijay_V2.pdfNitrogen Ion Implantation Optimization
Nitrogen Ion Implantation Optimization
Nitrogen (N) ion implantation conditions (dose and energy) into p-type, Mg-doped GaN was optimized through simulation with the goal of producing a box profile with a ~500nm depth. N ion implantation within p-GaN results in compensation. This method is used to produce guard rings for electric field management within vertical GaN power devices.
Spring 2023
Vijay_Lithography Project Report V1.pdfLithography Process and Photomask Design Optimization
Lithography Process and Photomask Design Optimization
A term project optimizing an intended mask design for 193 nm immersion lithography. Numerical aperture (NA), light coherence, phase-shift masking and optical proximity correction were explored through Athena Silvaco simulations to achieve the intended feature dimensions and feature shape. The resist profile amd exposure dose conditions were also optimized via Silvaco simulations.
