| Abstract(in English) | Ultrafast carrier motion in the femtosecond time regime accompanies electromagnetic wave radiation that is proportional to carrier acceleration. Investigation of such terahertz (THz) radiation allows us a very unique opportunity of quantitative analysis of nonstationary carrier transport and terahertz conductivities in ultrafast semiconductor devices. We have utilized this technique to characterize Bloch gain in semiconductor superlattices and presented firm evidence that Bloch oscillating electrons have a gain up to a few THz. |
