Electronic Structure and Transport Properties of Graphene on Hexagonal Boron Nitride
Presentation Materials | 06 Dec 2018 | Contributor(s):: Shukai Yao, Luis Regalado Bermejo, Alejandro Strachan
Graphene is a zero-bandgap conductor with high carrier mobility. It is desired to search for an opening of band structure of graphene such that this kind of material can be applied in electronic devices. Depositing hexagonal Boron Nitride (h-BN) opens a bandgap in the band structure of...

DFT Study of Anisotropic Elastic Property of LiCoO2 During Lithium Intercalation and Deintercalation Process
Presentation Materials | 06 Dec 2018 | Contributor(s):: Lingbin Meng, Alejandro Strachan
Lithium cobalt oxide (LiCoO2) is a popular cathode material of lithium-ion batteries due to its excellent electrochemical properties. In this study, the anisotropic elastic property of LiCoO2 has been studied by comparing the ratio of C11 and C33 between LiCoO2 and CoO2. As a result, the...

Tight Binding Parameters by DFT mapping
Presentation Materials | 12 Sep 2012 | Contributor(s):: Yaohua Tan, Michael Povolotskyi, Tillmann Christoph Kubis, Yu He, Zhengping Jiang, Timothy Boykin, Gerhard Klimeck
The Empirical Tight Binding(ETB) method is widely used in atomistic device simulations. The reliability of such simulations depends very strongly on the choice of basis sets and the ETB parameters. The traditional way of obtaining the ETB parameters is by fitting to experiment data,or critical...
