Using the Büttiker-Landauer formulation of transport theory in the linear response regime, the valley currents and non-local resistances of bilayer graphene nanostructures with broken inversion symmetry are calculated. It is shown that broken inversion symmetry in bilayer graphene nanostructures leads to striking enhancement of the non-local 4-terminal resistance and to valley currents...
Nanomechanical devices have allowed for the study of the motion of macroscopic objects near their quantum ground state for mechanical motion. Coupling these devices to resonant electrical circuits provides a method of measuring with standard laboratory electronics, and a means to interact and cool towards the ground state. We report on current work, in microwave $L C$ resonators, using...
Graphene is an ideal material for high quality nano-electro-mechanical resonators due to its high Young's modulus, low mass to surface ratio, ability to sustain high in-plane strain, and unique electrical properties like high carrier mobility, ballistic transport and nonlinear modulation of conductance under the electric field effect. In this work, atmospheric pressure chemical vapour...
Silicon quantum dots (QD) stimulated to form excitons can decay by emitting a photon at a wavelength determined by it’s size, or tunnel to another QD. Films of a-SiO2 on Si wafer were subject to (<1MeV) Si+ implantation and annealed to form QD in a dielectric matrix. The density of implanted Si+ is non-uniform with respect to depth into the film, as are the densities of ionizations and atomic...
Experimental measurements of the speed distribution of atoms in an equilibrium gas agree with the predicted Maxwell-Boltzmann (MB) distribution from kinetic theory. It has been almost universally presumed that the MB distribution also applies to vapour atoms that are ballistically ejected into vacuum from liquid or solid surfaces, calculated assuming that the vapour is an equilibrium gas with...
Ultrathin film materials have attracted significant attention in light of their potential applications in integrated electronics and data storage. The amount of data that can be addressed and stored in resistive memory devices scales inversely with their thickness, and ultrathin thermal sinks are required to evacuate heat from such electronic components. So far, virtually any techniques used...
The use of silicon (Si) in optical and optoelectronic devices depends heavily on the development of a Si-based light source. The ability to use Si in such applications will have many advantages, including low fabrication cost and high compatibility with existing technology. Therefore, researchers have explored the use of various techniques to improve the inherently poor luminescence of bulk...
