Boron acceptor

WebThe con centrations correlate with the boron content in a growth mixture. Minimum donor to acceptor compensation ratio slightly below 1 % was observed at 0.002 at.% boron content in a growth mixture, while it increased at an increase and decrease of boron amount. Samples grown at such boron concentration had maximum carrier mobility.
