Impurity trap
Witryna1 lut 2003 · The effects of impurity trap levels on MOSFET gate current and trapped charge are analyzed in this work. It is found that the impurity atoms with trap energy levels closer to the SiO 2 conduction band greatly affect the gate current and trapped charge density and hence the speed of the device. WitrynaIf an impurity atom, often called a dopant, is present in a semiconductor (which is then designated as doped) and has a different number of valence electrons from the atom it replaces, extra energy levels can be formed within the band gap. ... Only by supplying energy corresponding to E can the electron leave the trap and return via the ...
