    • The quantum fine line manufacturing method is comprised of the step of (a) growing AlGaAs layer(20) on a GaAs substrate(10), then forming a photoresist mask(30) for digging a V-groove in [011 direction on the AlGaAs layer(20) by means of the photolithography, the step of (b) etching with etching solution which has volume ratio of H2SO4:H2O2:H2O=1:2:40 to form the V-groove, the step of (c) growing a plurality of GaAs(50) and AlGaAa(40) layers by means of the epitaxial growth method on the substrate where the V-groove is formed to form the quantum fine line(QWRs) in the center of the V-groove. Here, a side quantum well(side-MQWL) is formed in both sides of the quantum fine line simultaneously and a top quantum well(top-MQWL) is formed in the outside of the V-groove simultaneously.
    • 量子细线制造方法包括以下步骤:(a)在GaAs衬底(10)上生长AlGaAs层(20),然后在AlGaAs的[011方向上形成用于挖掘V形槽的光致抗蚀剂掩模(30) (20),步骤(b)用H 2 SO 4 :H 2 O 2 :H 2 O = 1:2:40的体积比的蚀刻溶液蚀刻以形成V形槽,(c)生长步骤 通过外延生长法在多个GaAs(50)和AlGaAa(40)层上形成量子微细线(QWR)的衬底上形成V形槽,其中V型槽的中心。 这里,同时在量子微细线的两侧形成侧面量子阱(侧面MQWL),同时在V形槽的外侧形成顶部量子阱(顶部MQWL)。
