The thing you have to realise is that semiconductor junctions have an approximately exponential relationship between voltage and current, so you cannot simply apply a voltage to them and expect to be able to predict the current.
22.
But, in practice, surface impurities within the part of the semiconductor that touches the metal terminals will greatly reduce the width of those depletion layers to such an extent that the metal-semiconductor junctions do not act as diodes.
23.
BJTs come in two types, or polarities, known as PNP and NPN based on the 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.

While there are specialised instruments to detect short-circuits between adjacent PCB tracks, an ESR meter is useful because it can measure low resistances while injecting a voltage too low to confuse readings by switching on semiconductor junctions in the circuit.
26.
The first theory that predicted the correct direction of rectification of the metal semiconductor junction was given by drift currents of the majority carriers through the semiconductor surface space charge layer which has been known since about 1948 as the Mott barrier.
27.
Also, "'any "'radio is composed of active semiconductors and there are devices that detect the presence of semiconductor junctions by means of the effect that they have on radio fields ( notably, the generation of harmonics of the fundamental frequency of the radio field ).
28.
The subarsenide B 12 As 2 may be an attractive choice for devices exposed to radiation which degrades the electrical properties of conventional semiconductors, such as betavoltaic cells, which generate electrical energy by coupling a radioactive beta emitter to a semiconductor junction, and other space electronics.
29.
They are of high electrical resistance higher than typical resistance materials, but still of much lower resistance than doping " ) into the crystal structure, which lowers its resistance but also permits the creation of semiconductor junctions between differently-doped regions of the extrinsic semiconductor crystal.
30.
In semiconductor physics, the primary use of the electron affinity is not actually in the analysis of semiconductor vacuum surfaces, but rather in heuristic electron affinity rules for estimating the band bending that occurs at the interface of two materials, in particular metal semiconductor junctions and semiconductor heterojunctions.
