Abstract
An integrated circuit bulk substrate having a zinc blende or Wurtzite crystalline structure is alloyed with a material having atoms that replace atoms of the host semiconductor. The alloyed atoms have a bond length with the nearest neighboring host atoms that is less than the bond length of the host atoms. The number of bonded alloyed atoms is small compared to the number of host atoms so as not to substantially affect electronic conduction properties of the host material, but is large enough to virtually eliminate dislocations over a large surface area and volume of the host material on which active semiconductor devices are located.
