The two basic types of transistors are the NPN transistorand the PNP transistor. Certainly there are many other semiconductor devices, but these are arguably the two basic ones.
integrated circuit
Resistors, capacitors, inductors, transformers, diodes, transistors, integrated circuits, power sources are the basic building blocks.
A fridge may or may not have a few transistors in it, these are electrical components that would probably be part of the control circuitry. Transistors used to be very common components of most electrical appliances. The cooling process of the fridge has nothing to do with transistors and is handled by a compressor and a heat exchange pump

Silicon
The basic components of a transmitter are; transistors, capacitors, resistors, condenser, Inductor, and antenna.

Modern silicon transistors are by layering a semi conductor material on top of a conductor material on top of a semi conductor material. Various materials have been tried to improve the effeciency of the transistor. Most transistors these days come as part of an intergrated circuit or IC
transistor are materials they have to be extracted and purified this relies on chemistry and material science
Basically, in transistor, the signal is transferred from low resistance circuit to the high resistance circuit. So it is called transfer+resistor=Transistor.Transistors are widely used in different types of switching, amplifiers, oscillators and integrated circuits.Based on the applications, the types of the transistors are as given below:General purpose transistors, Low frequency transistors, High frequency transistors, Power transistors, Switching transistors, Field Effect Transistors, MOSFET, Uni-junction Transistors, Bi junction transistors, Photo transistor, High power transistors, Complementary pair, Darlington amplifier, Video and R.F. amplifier, Ultrahigh frequency and microwave, Insulated gate bipolar transistors, Static induction transistors.More their to know about transistors are as given below:History of invention, Time-line throughout, Basic construction, Bias arrangement, working, Various currents in transistors, Basic transistor amplifier, Configurations, Characteristics, Current gain and relation among them, D.C. load line, Operating point, Biasing of transistor, stability factor, specifications and ratings, testing, colour coding, identification of transistor using multimeter, h-parameter of transistor, particular applications etc...
Integrated Circuit is not exactly correct. The circuit contains 100s and even 1000s of Transistors. The transistor is the basic building block.
Transistors provide most of the activities a circuit needs to operate. In their most basic representation, transistors are amplifiers. That is, they take and amplify a signal from the level produced by a microphone and amplify it enough to blast it out through a speaker. Transistors are also used on decision making circuits, like electronic gates and Central Processing Units (CPUs). Solid state, electronic systems like desktop computers, cell phones, and GPS devices would not be possible without transistors.
Transistors have two basic functions: # an electrically controlled electric switch # an electrically controlled "proportional valve" which can alter currents and voltages, or can amplify electric signals. Transistors can also be configured as Oscillators which provide an AC signal with constant frequency. Either an amplifier circuit or a switching circuit can be wired as an oscillator. Transistors can be used to form logic gates: And, Or, and Invert. Computers are made from logic gates, so computers can be made entirely from transistors. Transistors are in use in virtually all electronic devices. PC processors are composed of millions of tiny transistors. A transistor radio may have had only 6-10 transistors to enable operation. A late model car may have 10 to 15 computers comprised of thousands of transistors to perform all manner of operations in the vehicle.

The use of substrate in Field Effect Transistors is for it to serve as insulating material between the gate and the source.
