Diffusion-Reaction Modeling of Cu Migration in CdTe Solar Devices

22 Apr 2016 | Online Presentations | Contributor(s): Da GUO, Tian Fang, Richard Akis, Dragica Vasileska

IWCE 2015 presentation. In this work, we report on development of one-dimensional (1D) finite-difference and two- dimensional (2D) finite-element diffusion-reaction simulators to investigate mechanisms behind Cu- related metastabilities observed in CdTe solar cells [1]. The evolution of CdTe solar cells performance has been studied as a function of stress time in re- sponse to the evolution of associated acceptor and donor states. To achieve such capability, the simu- lators solve...

Multi-Scale Modeling of Self-Heating Effects in Nano-Devices

21 Apr 2016 | Online Presentations | Contributor(s): Suleman Sami Qazi, Akash Anil Laturia, Robin Louis Daugherty, Katerina Raleva, Dragica Vasileska

IWCE 2015 presentation. This paper discusses a multi-scale device modeling scheme for analyzing self-heating effects in nanoscale silicon devices. A 2D/3D particle-based device simulator is self-consistently coupled to an energy balance solver for the acoustic and optical phonon bath. This simulator is used to analyze the hot-spot temperature and location in various SOI devices, dual gate structures and nanowire transistors. This device simulator has been coupled to a SILVACO simulation tool...
