Abstract :
The present work is aimed to investigate the electron emission from DX centers in tellurium-doped AlxGa1−x As with aluminium composition x = 0.40 using deep-level transient spectroscopy. Evidence that Te-DX exhibits an alloy splitting is shown from the temperature-dependent emission at a given reverse bias. The Poole–Frenkel effect was evoked to explain the electric field-enhanced emission. A discrepancy to this model is observed from experimental results. An attempt to explain this discrepancy as due mainly to the short-range character of the Te-DX-related potential.
