We point out that the effective channel of the Kapitza thermal conductance(KTC)of metal-nonmetal interfaces is governed by the electron-phonon coupling mediated by the metal-induced gap states allowed
Microcavities(MCs)with gain media have drawn much attention due to their significant applications in optoelectric devices,such as low threshold semiconductor lasers,opticalmemories and photonic integr
NiNb2O6 is a quasi-1D S=1 Heisenberg antiferromagnet with dominant ferromagnetic interactions along the chain.Here we report our studies of the magnetic properties on NiNb2O6 single crystals by the ma
自旋霍尔效应(Spin Hall Effect、SHE)是通过自旋轨道相互作用,将电荷流转化为纯自旋流,转化效率用自旋霍尔角来衡量.强自旋轨道耦合的重金属具有较大的自旋霍尔角,如Pt(0.08)、Ta(0.15)、W(0.3),而3d元素Cu的自旋霍尔角非常小.在金属Cu中掺杂能够增大Cu的自旋霍尔角,理论预言,通过调节表面也可改变Cu的自旋霍尔角.
