... Si-based optoelectronics, Ge quantum dots (QDs) in Si matrices have a ttracted a large interest during the past years. Detailed knowledge on the elec- tronic band structure and related optical transitions ... was measured in a short circuit configura- tion. A 2-mm-thick Si wafer serving as a filter was introduced to remove the strong PC signal due to the band-to-band...

During in situ STM observation (a tip bias was ?1.0 V, a tunneling current was 0.4 nA, and the scan speed was ... image. After a thermal drift reducing, using the STM tip, we applied voltage ‘from a reverse bias to a forward bias’. The time of applying voltage was 0.052 s, and a voltage val...
