Abstract

We introduce a solid-state version of ballistic electron emission microscopy/spectroscopy (BEEM/ BEES) on GaAs-AlGaAs heterostructures using a metal-insulator-metal (MIM) injector structure that replaces the tip of the scanning tunneling microscope (STM). In the present work, the MIM injector is realized by an Al-Al2O3-Al tunnel junction yielding an easy-to-fabricate three-terminal device for ballistic electron spectroscopy. The device principle is applied to several GaAs-AlGaAs structures. The barrier heights obtained from the onsets of the ballistic current spectra are in good agreement with self-consistent calculations as well as earlier experimental results achieved with STM-based BEES. © 1999 American Institute of Physics.
