Research Abstract

In this research project, we investigated dynamical conductivities in quantum nanostructures by using terahertz (THz) radiation as a probe for ultrafast carrier motion. The main results are ;
1.Carrier dynamics in semiconductor superlattices and THz gain of Bloch oscillating electrons : By analyzing the THz waveforms emitted from semiconductor superlattices pumped by femtosecond laser pulses, we have shown that Bloch oscillating electrons have dispersive THz gain for the first time. Furthermore, the dominant dephasing mechanism of Bloch oscillation has been identified to be interface roughness scattering.
2.Non-equilibrium transport in ultrafast transistors: To understand the performance of ultrafast transistors, we have investigated the THz radiation from non-equilibrium transport in bulk GaAs. It is found that the initial acceleration of photoexcited electrons starts to decrease with increasing field above 50 kV/cm, suggesting the importance of band mixing effect. Furthermore, we proposed a novel method to characterize the cutoff frequencies of ultrafast transistors beyond the frequency region accessible by conventional network analyzers.
3.Conduction dynamics of single molecule/dot junctions : We planned to investigate the conduction dynamics of nanojunctions in which single molecules or quantum dots are probed by nanogap electrodes. Although we could measure dc characteristics, THz dynamics could not be characterized mainly due to their stability problem. This sub-project is being continued in our new project "Physics and control of terahertz dynamics of quantum nanosystems" (Grant in Aid No.18201027).
