摘要：

Geometrically symmetric double-heterojunction bipolar transistors which have been fabricated in InGaP/GaAs show up differences in the shapes of output characteristics of the devices. This electrical asymmetry has been interpreted in terms of the lower junction being compositionally abrupt while the upper junction is graded. The differences in the junctions have been related to the sequence of growth of the layers.
