    • A resonant tunneling permeable base transistor has been realized experimentally by overgrowing a tungsten grating placed in direct vicinity to a double barrier heterostructure. In this way, we can directly modulate the tunneling current via an embedded gate. Since the quality of the overgrown interface is critical, special attention is paid to this issue, and the effect of different wet etchants prior to overgrowth is studied both by electrical measurements and by the use of an atomic force microscope. A clear dependence of the electrical properties and the crystal quality on the etchants used is found. This is a key result for the realization of our resonant tunneling device.

  • Three-dimensional integrated resonant tunneling transistor with multiple peaks
  • 2002
  • In: Applied Physics Letters. - : AIP Publishing. - 0003-6951 .- 1077-3118. ; 81:10, s. 1905-1907
  • Journal article (peer-reviewed)abstract
    • A resonant tunneling transistor was manufactured by integrating a self-aligned metallic gate 30 nm above and 100 nm below resonant tunneling diodes. The Schottky depletion around the gate controls the current to a confined vertical channel with a conduction area in the range of 100x100 nm. Due to the three-dimensional asymmetric placement of the gate with respect to the tunneling diodes, modulation of both the peak voltage and peak current was achieved.
