Influence of Dimensionality on Thermoelectric Device Performance
Raseong Kim, Supriyo Datta, Mark S. Lundstrom
The role of dimensionality on the electronic performance of thermoelectric devices is clarified using the Landauer formalism, which shows that the thermoelectric coefficients are r…
Spin Transfer Torque as a Non-Conservative Pseudo-Field
Sayeef Salahuddin, Deepanjan Datta, Supriyo Datta
In this paper we show that the spin transfer torque can be described by a pseudo magnetic field, proportional to the magnetic moment of the itinerant electrons that enters the Land…
Electronic transport driven spin-dynamics
L. Siddiqui, D. Saha, S. Datta +1
We propose a model to explore the dynamics of spin-systems coupled by exchange interaction to the conduction band electrons of a semiconductor material that forms the channel in a…
Conductance asymmetry of graphene pn junction
Tony Low, Seokmin Hong, Joerg Appenzeller +2
We use the non-equilibrium Green function (NEGF) method in the ballistic limit to provide a quantitative description of the conductance of graphene pn junctions - an important buil…
Electrically driven magnetization of diluted magnetic semiconductors actuated by Overhauser effect
L. Siddiqui, A. N. M. Zainuddin, S. Datta
It is well-known that the Curie temperature, and hence the magnetization, in diluted magnetic semiconductor (DMS) like GaMnAs can be controlled by changing the equilibr…
Nanoelectronic Devices: A Unified View
Supriyo Datta
Nanoscale electronic devices are of great interest for all kinds of applications like switching, energy conversion and sensing. The objective of this chapter, however, is not to di…
