In this paper, we report systematic investigation of the structural and electronic properties of GaN and InxGa1-xN alloys with x up to 0.31 grown on Si (111) substrate. P-type doping of InxGa1-xN using Mg has been achieved consistently with magnesium

A new alloy system, the GaN(sub 1-x)As(sub x) alloys in the whole composition range was successfully synthesized using the non-equilibrium low temperature molecular beam epitaxy method. The alloys are amorphous in the composition range of 0.17 x 0.75

Using plasma-assisted molecular beam epitaxy (PA-MBE), high quality InxGa1-xN layers with x in the range from 25 to 31% have been grown on silicon (111) substrates. The polarity of the layers has been found to impact the incorporation of In, with Ga
