Doped

An NPN transistor comprises two semiconductor junctions that share a thin p-doped anode region, and a PNP transistor comprises two semiconductor junctions that share a thin n-doped cathode region.

As the P-doped layer supplies holes to the depleted region, negative dopant ions are left behind in the P-doped layer ('P' for positive charge-carrier ions).

Boron nitride can be doped p-type with beryllium and n-type with boron, sulfur, silicon or if co-doped with carbon and nitrogen.

NPN is one of the two types of bipolar transistors, consisting of a layer of P- doped semiconductor (the "base") between two N-doped layers.

Semiconductors doped with donor impurities are called n-type, while those doped with acceptor impurities are known as p-type.

The clocking of the gates, alternately high and low, will forward and reverse bias the diode that is provided by the buried channel (n-doped) and the epitaxial layer (p-doped).

The emitter is heavily doped, while the collector is lightly doped, allowing a large reverse bias voltage to be applied before the collector–base junction breaks down.

The n-doped germanium would have an excess of electrons, and the p-doped germanium would have an excess of holes.

The other type of BJT is the PNP, consisting of a layer of N- doped semiconductor between two layers of P-doped material.

Therefore, a silicon crystal doped with boron creates a p-type semiconductor whereas one doped with phosphorus results in an n-type material.

When a p–n junction is first created, conduction-band (mobile) electrons from the N- doped region diffuse into the P- doped region where there is a large population of holes (vacant places for electrons) with which the electrons "recombine".

In the minutes before the race poor Plenipo showed every sign of having been doped and he finished unplaced behind a 40-1 chance.

I remember a time before anyone knew of ADHD, and kids weren't doped.

So I've been told at the beginning that it's a very, it's an extremely low quantity of this substance, a banned substance, and in those three days I could not have doped.

A research group led by Professor Yejing Dai from Sun Yat-sen University in Shenzhen, China, recently reported a new non-equivalent co-doped strategy for BIT-based high-temperature piezoelectric ceramics to solve the above mentioned problems.

I also suspect that many in government foolishly reckon that a doped population will be too apathetic to be discontented.

The gradient Ta-doped homojunction nanorods results in high conductivity inside (heavy Ta5+ doping) while the surface states outside were passivated by the removal of surface defects caused by heavy Ta5+ doping.

The greatest testament to is that even though Officer Lucy Chen had been doped by a “date,” hauled in a trunk to parts unknown and then tied up, we never wrote her off.

Beginning near the end of last decade, a spell of investigative reports exposed how racehorses were doped up during their careers and became an afterthought once those careers were finished.

Sun said he was taking medication for a heart condition and had not deliberately doped.
