We found that the streaming effect can occur in high-mobility heterostructures (μ⩾30 000 cm2/V s) with low electron concentrations (n⩽1012 cm−2) at temperatures above 77 K. The effect holds in the electric fields of a few kV/cm. These conditions can be met in contemporary high-quality nitride heterostructures that have advantages over the bulk materials due to the specifics of electron–phonon and electron–electron interactions in two-dimensional structures. Subsequently, the streaming effect may enable the development of electrically-pumped THz sources operating above the nitrogen temperature based on nitride heterostructures.Read More
