Abstract(in English) | We introduced TCA for heteroepitaxial growth of GaAs on Si, for obtaining lower dislocation density. The temperature of TCA which we have so far introduced is 350℃~850℃. In this study, by introducing TCA of 300℃~l000℃, we confirmed not merely the decrease in the dislocation density but the improvement of the surface roughness of GaAs on Si. By using the TCA of 300℃~1000℃, we confirmed the improvement of reflectivity spectra of AlAs/Al_<0.1>Ga_<0.9>As DBR. In addition, In_<0.02>Ga_<0.98>As 10QWs VCSEL on Si exhibits a cw threshold current of 102mA (6.19kA/cm-2) at 230K. |
