Valley Dependent g-factors in Silicon: Role of Spin-Orbit and Micromagnets
13 Dec 2016 | | Contributor(s):: Rajib Rahman
In this talk I will show that spin splittings in silicon quantum dots are inherently valley-dependent. Interface disorder, such as monoatomic steps, can strongly affect the intrinsic spin-orbit coupling and can cause device-to-device variations in g-factors. I will also describe the anisotropy...
Tutorial Introduction to Topological Insulators
08 May 2014 | | 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...
