A silicon transistor is a transistor made of silicon.
The sum of (base current) plus (collector current).
Similar to a 2N3906 PNP transistor
it represents one junction
I believe that is resistor transistor technology TTL transistor transistor logic
Base of transistor is made thin just to get Collector current equal to Emitter current.
two The transistor has one depletion layer.
The input current of transistor is approximately equal to output current .Suppose in common base configuration the emmiter current is approximately equal to collector current if neglect the very small value of bae current.Even though the input resistance is not equal to output resistance,the currents are same ,so we can reliase that the transistor transfers resistance to get same currents at both ends.
An unbiased transistor is one being used with no bias voltage to offset its operating point. If the input signal is very small it still can operate as an amplifier but the output will be non-linear. One use for an unbiased transistor is when the transistor is used as a switch, turning it on or off.
a thyristor can be considered as two complementary transistors , one pnp- transistor, and other npn transistor
There wouldn't be any reason for one.

Because they are different transistors. Resistance among their internal diodes is one of the main features of a transistor.
When investigated with an ohm-meter, a transistor resembles two diodes connected "back-to-back". But you can't make a transistor by connecting two diodes back-to-back.
http://www.vias.org/transistor_basics/transistor_basics_04_05_03.html The minimum signal that can be applied to a transistor is limited by the internal noise generated by the transistor. Since the transistor does not require cathode heating (one of the major noise sources in the vacuum tubes), it is inherently capable of operating at lower noise levels than its vacuum tube brother. At present, the junction transistor is equal to the vacuum tube, insofar as its noise characteristics are concerned. The noise level of the point-contact types is between 15 and 30 db higher. see the website, there is a lot more. do more research for certainty.
A Darlington transistor it may contain one or more transistor in its case. the purpose is to amplify current by beta multiplication.
