Tutorial Introduction to Topological Insulators
08 May 2014 | Online Presentations | Contributor(s): Parijat Sengupta
An important pursuit in semiconductor physics is to discover new materials to sustain the continuous progress and improvements in the current electronic devices.Traditionally, three material types are in use: 1) Metals 2) Semiconductors 3) Insulators. All the three material types are classified...

Nanoelectronic Modeling Lecture 11: Open 1D Systems - The Transfer Matrix Method
31 Dec 2009 | Online Presentations | Contributor(s): Gerhard Klimeck, Dragica Vasileska, Samarth Agarwal, Parijat Sengupta
The transfer matrix approach is analytically exact, and “arbitrary” heterostructures can apparently be handled through the discretization of potential changes. The approach appears to be quite appealing. However, the approach is inherently unstable for realistically extended devices which...
