The learn of deep degrees in semiconductors has visible massive development in recent times. Many new suggestions became on hand for investigating either the digital houses of deep degrees and the chemical nature of the defects from which they come up. This expanding curiosity has been encouraged by way of the significance of the topic to equipment know-how, particularly these microwave and opto-electronic units made of GaAs, InP and their alloys. whereas earlier meetings have coated professional parts of deep point expertise, the assembly defined right here was once prepared to attract jointly staff from those separate fields of analysis. the subsequent papers replicate the breadth of pursuits represented on the convention. For the sake of uniformity we now have selected the English substitute the place an American expression has been used. we've got additionally sought to enhance grammar, occasionally with out the approval of the writer within the pursuits of swift book. The Editor needs to thank the referees for his or her prepared suggestion in any respect levels, Paul Jay who helped with a few of the editorial tasks and Muriel Howes and Lorraine Jones for speedy and actual typing.
