    • PURPOSE: A laser diode using zinc oxide nanorods and a manufacturing method thereof are provided to perform UV laser oscillation in room temperature by improving the doping of a P-type semiconductor of a zinc oxide. CONSTITUTION: A substrate(10) is made of either metal, silicon, glass, or graphite. An electrode layer(20) is formed on the substrate. A nanorods layer(30) includes a plurality of zinc oxide nanorodses which is grown up on the electrode layer. A plurality of zinc oxide nanorodses is doped to an n-type. The zinc oxide nanorodses can be aligned perpendicular to the substrate. A single crystal semiconductor layer(40) can be either a single-crystal silicon substrate doped to a p-type, a GaAs substrate, or a GaN substrate. The single crystal semiconductor layer contacts the top of a nanorods layer in an interface(50).
    • 目的:提供使用氧化锌纳米棒的激光二极管及其制造方法,通过改善氧化锌的P型半导体的掺杂,在室温下进行紫外激光振荡。 构成:衬底(10)由金属,硅,玻璃或石墨制成。 在基板上形成电极层(20)。 纳米棒层(30)包括在电极层上生长的多个氧化锌纳米棒。 多个氧化锌纳米棒被掺杂成n型。 氧化锌纳米棒可以垂直于衬底取向。 单晶半导体层(40)可以是掺杂到p型,GaAs衬底或GaN衬底的单晶硅衬底。 单晶半导体层在界面(50)中接触纳米棒层的顶部。
