The ballistic transport of hot electrons in semiconductors has long been a subject of interest. Over the last decade enormous progress has been made in the study of such transport using tunneling-based hot electron (or hole) injectors. In this talk, I will present several exciting new results which have broad implications for the study of new semiconductor nanostructures that feature the transport of spin. These are: (1) the development of Ballistic Electron Emission Luminescence (BEEL), a technique which allows the simultaneous monitoring of electron transport and luminescence for quantum dot structures placed below the surface; (2) the demonstration of several new types of hot electron based devices, such as spin valve photodiodes and avalanche spin valve transistors; and
(3) exciting new studies of transport and luminescence in semiconductor nanowires such as ZnON and GaN.
