In gallium arsenide (GaAs) MESFETs, which consequence results when the gate voltage exceeds the Schottky barrier?

💡 Explanation

Increased gate voltage beyond the Schottky barrier allows the thermionic emission mechanism to dominate, because electrons now have sufficient energy to overcome the barrier potential; therefore, gate current increases substantially, rather than drain modulation being affected or channel activity suppressed by the voltage.
