Abstract:
An electronic device comprising: a semiconductor body of silicon carbide, SiC, having a first and a second face, opposite to one another along a first direction, which presents positive-charge carriers at said first face that form a positive interface charge; a first conduction terminal, which extends at the first face of the semiconductor body; a second conduction terminal, which extends on the second face of the semiconductor body; a channel region in the semiconductor body, configured to house, in use, a flow of electrons between the first conduction terminal and the second conduction terminal; and a trapping layer, of insulating material, which extends in electrical contact with the semiconductor body at said channel region and is designed so as to present electron-trapping states that generate a negative charge such as to balance, at least in part, said positive interface charge.
