用常压MOCVD方法在GaAs(100)衬底上生长了CdZnTe/ZnTe多量子阱。在室温下,观测到了CdZnTe/ZnTe多量子阱的三个谱带发光。根据CdZnTe/ZnTe多量子阱的吸收光谱和不同激发光强下的发光光谱,分别归结CdZnTe/ZnTe多量子阱中观测到的三个发光谱带于覆盖层发光、n=1的重空穴激子发光及杂质发光。
CdZnTe / ZnTe multiple quantum wells were grown on GaAs (100) substrates by atmospheric MOCVD. Three bands of CdZnTe / ZnTe multiple quantum wells were observed to emit light at room temperature. According to the absorption spectra of CdZnTe / ZnTe multiple quantum wells and the luminescence spectra under different excitation intensities, the three luminescence bands observed in the CdZnTe / ZnTe multiple quantum wells are respectively luminescent and n = 1 heavy hole excitations Sub-glow and impurities glow.
