Can the interface between a non-ideal ferromagnet and a semiconductor quantum wire acts as an ideal spin filter?
Marc Cahay, Supriyo Bandyopadhyay
The problem of spin injection across the interface between a non-ideal ferromagnet (less than 100% spin polarization) and a semiconductor (paramagnetic) quantum wire is examined in…
When it comes to spintronics, there may be some room in the middle
S. Bandyopadhyay
Spintronic devices that utilize the spin degree of freedom of a charge carrier to store, process or transmit information, may be better performers than their traditional electronic…
Quantum Information Science from the Perspective of a Device and Materials Engineer
S. Bandyopadhyay
Quantum information science is presented in a fashion that may be useful to a device or materials engineer. Spintronic implementations are emphasized.
Spin fluctuations and spin noise
S. Pramanik, S. Bandyopadhyay
We have theoretically studied the temporal fluctuations and the resulting kinetic noise in the average spin polarization of an electron ensemble drifting in a quantum wire under a…
Effect of Disorder on the Conductance of Spin Field Effect Transistors (SPINFET)
M. Cahay, S. Bandyopadhyay
We show that the conductance of Spin Field Effect Transistors (SPINFET) [Datta and Das, Appl. Phys. Lett., Vol. 56, 665 (1990)] is affected by a single (non-magnetic) impurity in t…
Prospects for a Quantum Dynamic Random Access Memory (Q-DRAM)
S. Bandyopadhyay
Compared to quantum logic gates, quantum memory has received far less attention. Here, we explore the prognosis for a solid-state, scalable quantum dynamic random access memory (Q-…
