In the case of Bipolar Junction Transistor current conduction is due to both holes and electrons. That's why noise is high in Bipolar Junction Transistor

Yes, the are different names for the same thing.

A bipolar transistor uses both majority and minority charge carriers for conduction, while a field effect transistor primarily relies on majority charge carriers. Field effect transistors have a higher input impedance compared to bipolar transistors. Additionally, bipolar transistors are current-operated devices, while field effect transistors are voltage-operated devices.

The full form of igbt is insulated gate bipolar transistor.
it is constructed from the combining of both BJT and PMOSFET.
it has high input impedance and low on - state power loss .
it is free from second break down problem present in bjt...
it is also known as (MOSIGT), (COMFET)...
it is constructed virtualy in the same manner as a power
MOSFET.an IGBT has also thousand of basic structure cells
connected appropritely on a single chip of silicon.
it has a four substrate p,p+,n+,n-. respectively...
p+ substrate is called injection layer because it injects
holes into n- layer .n- layer is called drift region .
thickness of the n- layer determines the voltage blocking
capability of IGBT.
the p layer is called body of the IGBT.
WHERE IT IS USED : it is widely used in medium power
application such as DC and AC motors drives.
UPS SYSTEMS , RELAYS AND CONTACTORS.
In thyristor the gate is triggered the gate is losses its
control. ie if we remove the gate pulse after the thyristor
starts conducting it will not stop.
but in IGBT we can control the Gate. by applying reverse
voltage applied across it .
The Thyristors can not be switched beyond 1kHz where as
IGBTs can be switched upto 25kHz and even to 100KHz with
few soft switching techniques.
The thyristor can carry very high currents order of 3000A
but IGBT carries less current max of 1000A.
Thyristor commutation ,that is switching off is very
difficult. But there are applications of Thyristor with
natural commutation.
The IGBT can be switched on and off like a MOSFET. ie it is
voltage controlled device.

HEMT differs from BJT in following ways:
1. Unipolar device
2. Voltage Controlled device
3. Current is Controlled by Electric Field (FET)
4. 2 DEG is formed
5. High Mobility due to 2 DEG (Faster) etc
6. Source, Gate and Drain names for Emitter, Base, Collector
etc

A transistor acts like a resistor when Gate is connected to Source.
1 answer
A: Yes it can but why ?
This is frequently done when the diode is used for biasing purposes on another transistor and must be matched identically to the transistor's E-B junction characteristics. Thus 2 matched transistors are used with one just being used as a diode.
1 answer
BJT stands for bipolar junction transistor because it is composed of two types of semiconductors (P and N-type) rather than just one type like a unipolar transistor. This allows for both electron and hole current flow in the device, giving it its bipolar characteristic.

A normal configuration for a BJT is Class A Common Emitter. In this configuration, the BJT operates as an inverting amplifier. Driven into saturation, it is a inverting switch, hence the designation NOT gate.
Transistor can act as a gate. But its not a gate. In BJT(Bipolar Junction Transister) type transisters there are two P-N juntions. That means if we need we can use it as a NOT gate. Actually gate ICs (Intergrated circuits) are also build using transistors. (Example : TTL(transister-transister logic))

Transistor is called Bi-Polar device because the current can be flow due to electron and holes, hence it is called bipolar.
1 answer
In case of a bipolar junction transistor, we have only three terminals (legs). They are emitter, base and collector.
But, in case of a MOSFET (metal oxide semiconductor field effect transistor), we can have four legs. They are source, drain, gate and substrate. The substrate is not being shown in some notations of MOSFET. But it does exist. Hence, a MOSFET has four legs.

A circuit in which the input signal is applied to its base and the collector is earthed (grounded) is known as common collector configuration of BJT (BiPolar Junction Transistor)

Sort of. The Bipolar Junction Transistor, or BJT, is a type of transistor. But the term transistor applies to a much wider family of components than just the Standard BJT. A rough list of the other common types of transistors includes:
Field effect transistors, or FETs, including both Junction types and Metal-oxide Semiconductor types: JFETs and MOSFETs. and also UJTs or unijunction transistors.
In a basic electronics course, though, if you say just 'transistors' it is assumed you mean BJTs.

VCC is an electronics designation that refers to voltage from a power supply connected to the "collector" terminal of a bipolar transistor. In an NPN bipolar junction transistor, it would be +VCC, while in a PNP transistor, it would be VCC
