In semiconductor devices, leakage is a quantum phenomenon where mobile charge carriers (electrons or holes) tunnel through an insulating region. Leakage increases exponentially as the thickness of the insulating region decreases. Tunneling leakage can also occur across semiconductor junctions between heavily doped P-type and N-type semiconductors. Other than tunneling via the gate insulator or junctions, carriers can also leak between source and drain ter… WebMax. leakage current after 2 min. 2) (µA) "wet" Al-electrolytic capacitors 1976 3) Ethylene glycol/borax electrolyte: Valvo, 034, 4.7/40: 5x11: 15.000: 17: ...
