We propose a superradiant laser based on two-photon Raman transition of cesium -133 atoms which collectively emit photons on an ultra narrow transition into the mode of a low Q resonator known as opti
For a long communication distance,the divergence angle of laser transmitting by space laser communication system must be narrow to solve the energy problem.However,it need be magnified during the grou
The diffusion current is a difficult obstacle of electronic cochlea.The current diffusion in nerve tissue limits the number of implantable electrodes.It limits selectivity of the auditory nerve,affect
Barrier-free injections of electrons and holes, followed by effective confinement and radiative recombination of charge carriers, are critical for electroluminescent devices. Here, we utilize a struct
Graphitic carbon nitride (g-C3N4) is among the most promising metal-free photocatalysts for H2 production from solar-driven water reduction[1-2]. However, the photocatalytic efficiency of bulk g-C3N4
Resistive switching (RS) phenomenon induced by redox in oxide electrolyte shows fascinating prospects for potential applications in resistance random access memory (RRAM), analog circuits and neuromor
Normal metal (N) interfaces is the so-called spin mixing conductance that governs the absorbance of a transverse spin current and generation of spin transfer torque. The spin-mixing conductance is a p
