| Abstract(in English) | In order to investigate tunneling phenomena through quantum dots, we have investigated an InGaAs/InAlAs triple barrier resonant tunneling structure under presence of a strong pulse magnetic fields. We observed for the first time a total suppression of the nonresonant valley current, which indicates the existence of the so called phonon bottleneck effect in a magnetic confined quantum dot system. We also studied an advanced TSR quantum dot technology that enables control of electron confinement energy and fabrication of a multi stacked quantum dot structure. We found that by changing the flow rates of trimethylindium being used as an indium source or by changing the well thickness, the confinement energy of electrons in the quantum dot could be controlled. We fabricated for the first time a stacked, double AlGaAs/InGaAs TSR quantum dot resonant tunneling diode and measured clearly an NDR in the I-V characteristics. |
