澳大利亚莫那什大学和澳科工组织的联合攻关小组开发出一项生成高等级光电薄膜晶片的新技术,可使晶体的淀积层按预定的若干个原子厚度逐次生长出来。这种晶格可使电子在红外粒子的激励下流动,构成高红外敏感薄膜。该小组采用金属有机化学气相淀积方法,将碲化镉和碲化汞的晶体层均匀地逐层生长。该系统在相对低的温度和压力下淀积出的原子平均厚度为5000分之一mm。通过变 A joint research team from Australia’s Monash University and the Australian Institute of Science and Technology has developed a new technology for producing high-grade electro-optical thin-film wafers that can be grown one after another at predetermined atomic thicknesses. This lattice allows electrons to flow under the excitation of infrared particles to form a high-IR sensitive film. The group uses a metal-organic chemical vapor deposition method to grow the crystal layers of cadmium telluride and mercury telluride uniformly layer by layer. The average thickness of atoms deposited by the system at relatively low temperatures and pressures is one-fifth of a millimeter. Through change
