The etching result of 128 × 128 array ,in which the area of unit ceil was 25μm × 25μm, was studied. The profile angle was approximately 80°. There was a linear relationship between the etching depth and the etching time. The dependence of etching rate on NH4Cl solution concentration was also studied. The photoresponsivity of the array＇s unit cells was measured. The UV-to- visible rejection ratio was around 60 ： 1.展开更多
In this note,the authors resolve an evolutionary Wente's problem associated to heat equation,where the special integrability of det▽u for u∈H^1(R^2,R^2)is used.
