open-in-new
<p>A MESFET (metal–semiconductor field-effect transistor) is a <a href="/facts/Field-effect_transistor/TerYC6Nz">field-effect transistor</a> semiconductor device similar to a <a href="/facts/JFET/oo5QxmTK">JFET</a> with a <a href="/facts/Schottky_barrier/1a0QpU5x">Schottky</a> (<a href="/facts/Metal/PT8hNX6R">metal</a>–<a href="/facts/Semiconductor/zFf3mGTE">semiconductor</a>) junction instead of a <a href="/facts/P%25E2%2580%2593n_junction/CaKIdLPg">p–n junction</a> for a <a href="/facts/Gate_(transistor)/TerYC6Nz">gate</a>. </p>
