Comprehensive numerical analysis of doping controlled efficiency in lead free Cs(SnGe)I3 perovskites solar cell
Nazmul Hasan, M. Hussayeen Khan Anik, Mohammed Mehedi Hasan +2
One effective way to prevent toxicity and improve the stability of materials for photovoltaic applications is to exclude lead and organic molecules from perovskite materials. Speci…
Optical, Thermal, and Electrical Analysis of Perovskite Solar Cell with Grated CdS and Embedded Plasmonic Au Nanoparticles
Ohidul Islam, M. Hussayeen Khan Anik, Sakib Mahmud +3
We propose a novel approach to enhance the performance of perovskite solar cells (PSCs) by incorporating grated Cadmium Sulfide (CdS) and plasmonic gold nanoparticles (Au NPs) into…
Hysteresis-Free Nanosecond Pulsed Electrical Characterization of Top-Gated Graphene Transistors
Enrique A. Carrion, Andrey Y. Serov, Sharnali Islam +6
We measure top-gated graphene field effect transistors (GFETs) with nanosecond-range pulsed gate and drain voltages. Due to high-k dielectric or graphene imperfections, the drain c…
Role of Joule Heating on Current Saturation and Transient Behavior of Graphene Transistors
Sharnali Islam, Zuanyi Li, Vincent E. Dorgan +2
We use simulations to examine current saturation in sub-micron graphene transistors on SiO2/Si. We find self-heating is partly responsible for current saturation (lower output cond…
Transport in Nanoribbon Interconnects Obtained from Graphene Grown by Chemical Vapor Deposition
Ashkan Behnam, Austin S. Lyons, Myung-Ho Bae +4
We study graphene nanoribbon (GNR) interconnects obtained from graphene grown by chemical vapor deposition (CVD). We report low- and high-field electrical measurements over a wide…
Influence of Internal Fields on the Electronic Structure in Self-Assembled InAs/GaAs Quantum Dots
Sharnali Islam, Sasi Sundaresan, Shaikh Ahmed
Built-in electrostatic fields in Zincblende quantum dots originate mainly from - (1) the fundamental crystal atomicity and the interfaces between two dissimilar materials, (2) the…
