The double-heterostructure (DH) concept for lasers and light-emitting diodes (LEDs) grew out of the prelaser context of increasing the speed of the early bipolar junction transistors. The 1954 idea was to change the energy gap itself, with a graded-gap base, or a wide-gap emitter. This led to the 1957 more general concept of quasi-electric fields and potentials in structures with a position-dependent energy gap. This paper gives a personal chronological account of the evolution of these…

Band offsets and chemical bonding: the basis for heterostructure applications

The unifying concept underlying all heterostructure physics is the idea that energy gap variations act as quasi-electric forces on the electrons and holes in the structure, even in the absence of a
