Type IIb boron-doped diamond is a wonderful p-type semiconductor. You
can obtain metallic conductivities with a few hundred ppm doping.
There is no electronically useful n-type diamond.

You cannot grow diamond-Si heterostructures because,

   1) The lattice constants don't match.
   2) SiC forms.
   3) There is no way to grow microscopically perfect single crystal
diamond films a few nanometers thick on command.

Untutored idiot.
