Abiodun Salawu,Monica B. ChibitaWith the introduction of the concepts of the Pauli principle, the fermi level, energy bands and holes, we are now in a position to look in more detail at the behaviour of electrons and holes in semiconductors, which will lead to an understanding of the operation of devices — particularly diodes and transistors.

ogress with these new theoretical concepts was rapid, it was not until 1931, when A. H. Wilson published two papers in the . (entitled ‘The Theory of Electronic Semi-conductors’) that the theoretical basis of the electrical properties of solids was established.

or in 1948, though that epoch-making event was the result of far-sighted research planning by Bell Laboratories dating from a decade or more before: no mere chance discovery, therefore, but the fruition of work which allotted at its inception a vital role to materials. The transistor is now very old
