Impact ionization effect
WitrynaA model based upon an impact ionisation effect within the depletion layer gives a good fit to the practical observations. 11 The model proposes that leakage current arises because of the creation of extra electron-hole pairs within the depletion region due to impact ionisation by minority carrier electrons from the p-side. WitrynaThe Agilent 7200 GC–QTOF is the first commercial instrument that employs an electron impact ionization source in a tandem quadrupole time of flight mass spectrometer. The QTOF is a high-speed, full-spectrum (over a large mass range) detector capable of capturing high-resolution accurate mass measurements with MS–MS capabilities.
