InAs infrared-sensitive solar cells are fabricated by using the films grown by the liquid phase epitaxy technique.The film microstructures are characterized by
We build a sandwiched structure model in which the intergranular phase(IP) is homogeneously distributed between soft and hard magnetic grains, and gives a conti
A novel integratable and high speed InGaAsP multi-quantum well (MQW) complex-coupled distributed feedback (DFB) laser is successfully fabricated on a semi-insul
For high-quality superconducting tunnel junctions(STJS), it is necessary to reduce leakage current as much as possible.We describe the fabrication of niobium ST
A low-loss criterion for bend transitions in optical fibers is proposed. An optical fiber can be tightly bent with low loss to be adiabatic for the fundamental
A new method is proposed to describe quantum dynamical processes in finite space by using of a set ofdiscretized complete bases. In this method, the finite spac
