LP-MOVPE Ga1-xInxAs/InP量子阱结构材料
Ga1-xInxAs/InP Quantum Well Structure Grown by Low Pressure MOVPE
【摘要】 本文报道用低压金属有机化合物汽相外延(LP-MOVPE) 的方法生长了晶格匹配的Ga1-xIn4As/InP 量子阱结构材料.X光双晶衍射和透射电子显微镜测量表明多量子阱结构的周期性和界面质量较好、光致发光和光吸收谱的测量都观测到因量子尺寸效应导致的带间跃迁向高能方向的移动.
【Abstract】 Lattice-matched Ga1-xInxAs/InP quantum well structures were grown by low pressuremetalorganic vapor phase epitaxy (LP-MOVPE). Periodicity of the multi quantum well struc-tures and high quality of interfaces have been shown by X-ray double crystal diffraction andtransmission electron microscopy measurements. The shifts of the PL peaks to higher energiesinduced by quantum-size effect are observed. An exciton absorption peak is resolved ia 10Kabsorption spectrum.
