对2.5GDFB量子阱激光器p型低阻欧姆接触电极进行了研究,在退火温度400℃,退火时间30s进行快速热退火条件下,对AuPtTiInAsp+-InGaAs(掺Zn>1×1019cm-3)MQWnInP和AuPtTip+-InGaAs(掺Zn>1×1019cm-3)MQWnInP两种结构进行了p型欧姆接触试验研究,并对两者串联电阻进行了比较,其结果前者的串联电阻阻值为后者的1/4。
The p-type low-resistance ohmic contact electrode of 2.5GDFB quantum well laser was studied. Under the conditions of rapid thermal annealing at annealing temperature of 400 ℃ and annealing time of 30s, AuPtTiInAsp + -InGaAs (doped with Zn> 1 × 1019cm-3) MQWnInP and AuPtTip + -InGaAs (doped Zn> 1 × 1019cm-3) MQWnInP two structures were p-type ohmic contact test and The series resistance of the two were compared, the results of the former series resistance of the latter 1/4.
