Are used to study the structure, crystallograph quality, surface structure, conductivity and chemical status of grown films. The minimum full width at half maximum of XRD rocking curve of CdTe, ZnSe and ZnTe epilayers are 630, 133, 110 arcsec respectively. Compared to MBE and MOVPE, ICB allows the epitaxy at lower temperature onto various substrates with higher deposition rates.

实验在GaAs等衬底上分别生长了CdTe、ZnTe、ZnTe单晶薄膜，其X光摆动曲线半高宽分别达到了630、133和110弧秒，与MBE、MOVPE相比，ICB技术外延时，大幅度地降低了生长温度，提高了生长速率，在实际应用方面具有特别重要的意义。
