We describe the design, fabrication, and operation of a GaAs-based heterostructure device which
emits band gap luminescence from solid-state tunnel-junction ballistic injection of electrons with
sub-bandgap energy. We find that, due to energy conservation requirements, a collector bias
exceeding a threshold determined by the Schottky barrier height and sample band gap energy must
be applied for luminescence emission. The consequences of these results for a hybrid
scanning-probe microscopy and spectroscopy combining both ballistic electron emission
