Highly tunable spin-dependent electron transport through carbon atomic chains connecting two zigzag graphene nanoribbons
Highly tunable spin-dependent electron transport carbon atomic chains zigzag graphene nanoribbons
2012/2/27
Motivated by recent experiments of successfully carving out stable carbon atomic chains from graphene [Meyer et al. Nature (London) 454, 319 (2008); Jin et al. Phys. Rev. Lett. 102, 205501 (2009)] we ...
Spin exchange interaction with tunable range between graphene quantum dots
Spin exchange interaction tunable graphene quantum dots
2010/11/22
We study the spin exchange between two electrons localized in separate quantum dots in graphene.The electronic states in the conduction band are coupled indirectly by tunneling to a common continuum o...
Tunable band gaps in bilayer graphene-BN heterostructures
Tunable band gaps bilayer graphene-BN heterostructures
2010/11/19
We investigate band-gap tuning of bilayer graphene between hexagonal boron nitride sheets,
by external electric elds. Using density functional theory, we show that the gap is continuously tunable fr...
Tunable Vibrational Band Gaps in One-Dimensional Diatomic Granular Crystals with Three-Particle Unit Cells
Tunable Vibrational Band Gaps One-Dimensional Diatomic Granular Three-Particle Unit Cells
2010/11/18
We investigate the tunable vibration filtering properties of one-dimensional diatomic granular crystals composed of arrays of stainless steel spheres and cylinders interacting via Hertzian contact. Th...
Double quantum dot with tunable coupling in an enhancement-mode silicon metal-oxide semiconductor device with lateral geometry
Double quantum dot enhancement-mode silicon lateral geometry
2010/11/17
We present transport measurements of a tunable silicon metal-oxide-semiconductor double quantum dot device with lateral geometry. Experimentally extracted gate-to-dot capacitances show that the device...
Field-tunable stochasticity in the magnetization reversal of a cylindrical nanomagnet
Field-tunable stochasticity magnetization reversal
2010/11/18
The nature of magnetization reversal in an isolated cylindrical nanomagnet has been studied
employing time-resolved magnetoresistance measurement. We find that the reversal mode is highly
stochastic...
Room Temperature Coherent and Voltage Tunable Terahertz Emission from Nanometer-Sized Field Effect Transistors
Room Temperature Coherent Voltage Tunable Terahertz Emission
2010/11/24
We report on reflective electro-optic sampling measurements of TeraHertz emission from nanometer-gate-length InGaAs-based high electron mobility transistors. The room temperature coherent gate-voltage...
A superconducting qubit with Purcell protection and tunable coupling
superconducting qubit Purcell protection tunable coupling
2010/10/27
We present a superconducting qubit for the circuit quantum electrodynamics architecture that has a tunable coupling strength g. We show that this coupling strength can be tuned from zero to values tha...
