We study the effects of film thickness on lattice parameters,direct band gap and photovoltaic outputs in the sol-gel derived BiFeO3 thin films.With the change o
A ridge waveguide distributed-feedback laser emitting at 1064 nm is demonstrated.Two low-temperature-grown In0.21 Ga0.79As/GaAs quantum wells are employed as th
We successfully fabricate p-type ZnO∶N films by using rf magnetron sputtering and in situ annealing in O2 atmosphere.These p-type ZnO∶N films can be used as p
In order to improve the acceleration effect of corona discharge acting on air,we present an experimental study on the induced airflow produced by corona dischar
We show an effective method of healing the Stone-Wales (SW) defects through low energy electron irradiation using ab initio molecular dynamics simulation.The SW
An approximate collision-radiative method is developed to calculate energy level populations of atoms and applied to simulate radiative transfer in a shock laye
