摘要：
Nanometer resonant tunnelling diodes, with independent control of the electrodes and quantum well dimensionalities, have been fabricated by a novel technique. Liquid-helium temperature current-voltage (I-V) characteristics exhibit a set of resonance lines due to the tunnelling of the 3D electrode electrons through the 0D states of the quantum box. Preliminary results on the lineshape and the relative-intensity dependence of the lines on the radius of the box, and the principal quantum number, are discussed.
