A Physical Model for Non-Ohmic Shunt Conduction and Metastability in Amorphous Silicon Solar Cells
16 Aug 2011 | | Contributor(s):: Sourabh Dongaonkar, Souvik Mahapatra, Karthik Yogendra, Muhammad Alam
In this talk we develop a coherent physics based understanding of the shunt leakage problem in a-Si:H cells, and discuss its implications on cell and module level.Sourabh Dongaonkar is with School of Electrical and Computer Engineering, Purdue University, West Lafayette, INKarthik Y and Souvik...
Negative Bias Temperature Instability (NBTI) in p-MOSFETs: Characterization, Material/Process Dependence and Predictive Modeling (2011)
11 May 2011 | | Contributor(s):: Souvik Mahapatra
This is a presentation on Negative Bias Temperature Instability, or in short NBTI, observed in p channel MOSFET devices. Though NBTI has been discovered more than 40 years ago, in the last 10 years it has become a very important reliability concern as the industry moved from thicker SiO2 to...

From density functional theory to defect level in silicon: Does the “band gap problem” matter?
01 Oct 2008 | | Contributor(s):: Peter A. Schultz
Modeling the electrical effects of radiation damage in semiconductor devices requires a detailed description of the properties of point defects generated during and subsequent to irradiation. Such modeling requires physical parameters, such as defect electronic levels, to describe carrier...
