We report on InP-based metamorphic InGaAs photodiodes grown by gas source molecular beam epitaxy (MBE), in which a relatively thin compositional graded wide ban
Using three kinds of graphites with different graphitization degrees as carbon source and Fe-Ni alloy powder as catalyst, the synthesis of diamond crystals is p
The effects of electron-phonon interaction on energy levels of a polaron in a wurtzite nitride finite parabolic quantum well (PQW) are studied by using a modifi
We propose a simple mechanism for generating scale-free networks with degree exponent γ=3, where the new node is connected to the existing nodes by step-by-ste
