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...

Negative Differential Resistivity Exercise
28 Jun 2010 | Teaching Materials | Contributor(s): Gerhard Klimeck, Parijat Sengupta, Dragica Vasileska
In certain semiconductors such as GaAs and InP the average velocity as a function of field strength displays a maximum followed by a regime of decreasing velocity. Hilsum, Ridley, and Watkins postulated that peculiarities in the band structure of semiconductors would lead to the above phenomenon....
Crystal Viewer Lab Exercise
A central problem in the investigation of material properties involves the examination of the underlying blocks that aggregate to form macroscopic bodies. These underlying blocs own a definite arrangement that is repeated in three dimensions to give the crystal structure. We will try to explore...
