Outline of Final Research Achievements

The final goal of this study is realization of photoconductive antenna excited by optical light source with a wavelength at optical waveband region using dilute bismuthide (Bi-) semiconductors. In this study period, a Bi Knudsen cell was installed into a molecular beam epitaxial (MBE) growth machine in this researcher's group, and growth temperature dependence of crystalline state of low-temperature-grown (LTG) InGaAs was revealed for comparison of the case of LTG Bi-semiconductors. The results of this study provided guidelines for optimized MBE growth condition of LTG Bi-semiconductors.
