"I think it will be good news for minority carriers and bad news for a lot of bigger firms, " said Miller, the owner of C & AMP; D Carriers.
42.
A thin insulating layer, such as silicon dioxide, can reduce rates of electron-hole pair recombination and dark current by allowing the possibility of minority carriers to tunnel through this layer.
43.
"' Low level injection "'conditions for a P-N junction refers to the state where the number of minority carriers generated are small compared to the majority carriers of the material.
44.
The diode could also be integrated on the same die, it had a compact layout, it had no minority carrier charge storage, and it was faster than a conventional junction diode.
45.
In his patent the Schottky diode prevented the transistor from saturating by minimizing the forward bias on the collector-base transistor junction, thus reducing the minority carrier injection to a negligible amount.
46.
The Schottky diode could be integrated on the same die, it had a compact layout, it had no minority carrier charge storage, and it was faster than a conventional junction diode.
47.
Minority carriers play an important role in inversion layer ), so conventionally the source and drain designation for the carriers is adopted, and FETs are called " majority carrier " devices.
48.
This effect remained a mystery because nobody realised, until 1948, that Bray had observed minority carrier injection-the effect that was identified by William Shockley at Bell Labs and made the transistor a reality.
49.
For very high Schottky barriers where ? B is a significant fraction of the band gap of the semiconductor, the forward bias current may instead be carried " underneath " the Schottky barrier, as minority carriers in the semiconductor.
50.
Another example of frequency dependent capacitance occurs with MOS capacitors, where the slow generation of minority carriers means that at high frequencies the capacitance measures only the majority carrier response, while at low frequencies both types of carrier respond.
