Research Experience:

Dr. Uzair Majeed project involved the study of silicon nitride planar waveguides for optical waveguides applications. These optical waveguides could be used for biosensing applications alongwith an optical setup. The main idea was to develop multilayer planar structure which consists of silicon oxide/ silicon nitride and silicon oxide layer also called oxide/nitride/oxide (ONO) structure at low room temperatures and using simple and safe process. During this project he involved with several wafer cleaning procedures such as RCA cleaning, Piranha cleaning and ultrasonic cleaning using organic solvents. He worked in class 100 clean room and used fume hoods and accessories related to area such as organic solvents, strong acids, wafer cleaving kits and consumables. He also had access to deposition equipments named high temperature oxidation furnace and RF magnetron sputtering equipment. His sample characterization employed X-ray diffratction, Field emission scanning electron microscopy(FE-SEM), Energy dispersive x-ray (EDX) spectroscopy, Fourier transform infra red (FTIR)spectroscopy, Atomic force microscopy (AFM), Surface profiler, Spectral reflectance,
Ultraviolet visible (UV-VIS) spectrophotometer. My characterization also involved the spectroscopic ellipsometry and prism coupling technique which we got from Hungary and USA respectively.
