• Electron tunneling in the tight-binding approximation 

  Mackey, Frederick D. (University of Alabama Libraries, 2016)

  In this thesis, we treat tunneling similar to a scattering problem in which an incident wave on a barrier is partially transmitted and partially reflected. The transmission probability will be related to the conductance ...
• Search for effective spin injection heterostructures based on half-metal heusler alloys/gallium arsenide semiconductors: a theoretical investigation 

  Sivakumar, Chockalingam Sivakumar (University of Alabama Libraries, 2016)

  Efficient electrical spin injection from half-metal (HM) electrodes into semiconducting (SC) channel material is a desirable aspect in spintronics, but a challenging one. Half-metals based on the Heusler alloy family are ...
