Polyhedral shapes can be found in crystalline materials ranging from macroscopic natural mineral solids to microscopic or nanoscopic particles. These shapes originate from the crystallographic properties of the consti...
In the granite-NaF-H2O system, there exists a nucleation lag in the course of alkali feldspar crystallization indicated by experiments on crystallization kinetics. The nucleation lag time is about 18 h at 700℃ and ab...
The thermal instability of InP leads to the failure of vacuum deposition of this kind of compound films. Many results for the preparation of Ⅲ-Ⅴ compound films, such as GaAs, GaP and InAs, except InP by sputtering h...
