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…
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…
Spin Dephasing and Hot Spins
Supriyo Datta
At this summer school, I have tried to describe a general approach to quantum transport problems based on the Non-equilibrium Green Function (NEGF) method . I will not repeat this…
Atomistic Non-equilibrium Green s Function Simulations of Graphene Nano-Ribbons in the Quantum Hall Regime
Roksana Golizadeh-Mojarad, A. N. M. Zainuddin, Gerhard Klimeck +1
The quantum Hall effect in Graphene nano-ribbons (GNR) is investigated with the non-equilibrium Green s function (NEGF) based quantum transport model in the ballistic regime. The n…
Use of negative capacitance to provide a sub-threshold slope lower than 60 mV/decade
Sayeef Salahuddin, Supriyo Datta
It is well known that conventional Field Effect Transistors (FET's) require a change in the channel potential of at least 60 mV at 300K to effect a change in the current by a facto…
