what if compound has those metalloids(metal near stair case) with gas element, is it going to be semiconductor. Can you think of any other compound with metalloid and gas elements beside SiO2 that is insulator

Certainly I'm not an expert on semiconductors but I don't think adding a gas is what makes those metalloids semiconducting. I think its the Si + the doping element or the Ga + doping element. The way I understand it, the doping element is critical and the concn of the doping element is critical. And for insulators, aren't As3O3, As2O5, SnO2, SnO, etc insulators?
