It should be noted that while Si Schottky and GaAs Schottky devices are also majority carriers and their speed is also extremely high, they are limited to a blocking voltage of 250V.
In addition, reverse conduction during the dead-time is by majority carriers only, resulting in zero stored charge.
A strong DC bias causes majority carriers in the substrate to accumulate near the insulator interface.
2] is influenced by the integral coefficient of the majority carriers (holes for pnpn structures and electrons for the npnp structures) injection of junction J1, by the integral transfer coefficient of the minority carriers (holes for pnpn structures and electrons for the npnp structures) through wide base, and by the avalanche multiplication of charge carriers, taking place in the collector junction at relatively high forward voltages.
While the same must be true for bipolar junction transistors, the effect is mitigated by the bipolar phenomenon of conductivity modulation, whereby operation in the saturation region causes the injection of minority carriers into the collector region, resulting in a commensurate injection of majority carriers to preserve charge neutrality.
Alcatel's DynaMiTe ADSL chipset has been installed by the majority carriers in the US and also has wide usage in the Customer Premises Equipment (CPE) market with clients including Compaq, Flowpoint, Efficient, Zyxel, Cayman Systems, GVC, Teles and many others.
