In state-of-the-art processes, the gate dielectric is subject to many constraints, including: * Electrically clean interface to the substrate (low density of quantum states for electrons) * High capacitance, to increase the FET transconductance * High thickness, to avoid dielectric breakdown and leakage by quantum tun..."
