| Abstract: | The emission of terahertz radiation from a AlGaN/GaN heterostructure under the heating of two-dimensional electrons in a lateral
electric field is studied. The field dependence of the temperature of hot electrons is determined from an analysis of experimental
volt-ampere characteristics. A theoretical model of the thermal radiation of hot two-dimensional electrons is considered,
and the calculation results are compared with an experiment on terahertz radiation emission. |
