Abstract
Triisopropylindium ((CH.sub.3).sub.2 CH).sub.3 In is used as an n-type dopant for II/VI semiconductor materials. This dopant precursor is particularly suited for indium doping of II/V semiconductor materials at low carrier concentrations in the range of the low 10.sup.15 cm.sup.-3 and does not exhibit an appreciable memory effect.
