Nanoengineering Testbed for Nanosolar Cell and Piezoelectric Compounds

Abstract

This project designed nanoscale solar voltaic cells by using carbon nanotubes. The Field-Effect Transistor of carbon nanotube was adopted and asymmetric Schottky barriers made of two different metal-semiconductor barriers at both ends of carbon nanotubes were employed to enhance the Einstein photoelectric electron-hole separation. Two architectures of the nanoscale solar cell were designed and analyzed. This project also examined the use of finite element analysis to simulate the process of nanoindentation to gain insights into the behavior of elastoplastic and viscoelastic materials. The study examined the behavior of a calibrated elastoplastic material model during indentations using different indenter tip geometries. The study then compared simulations and experimental results for the elastoplastic material. Additionally, the study examined the calibration of a viscoelastic material model from reported data and its ability to predict indentation response.
