Surface chemistry of prototypical bulk II-VI and III-V semiconductors and implications for chemical sensing

A review of the issues associated with chemical sensing using single-crystal semiconductor substrates is made. First, the effects of adsorbates on the electronic structure of semiconductors are described. Following this, the techniques used to characterize the adsorbate-coated semiconductor surfaces are discussed. Further, various surface modification techniques and their effects on the semiconductor's electronic properties are highlighted.
