Avalanche photodiode
This lecture is about one of the types of photodiode i.e avalanche photodiode; it's definition, construction, functionality, working and later on it's mereits, demerits and applications
Construction and working
This lecture completes the topic of phototransistors: it's symbol, construction and working And moreover, it's advantages and disadvantages and applications of phototransistors
Quantum Efficiency and responsivity
Thare are the notes of a small topic in photodiodes i.e quantum efficiency and responsivity And to determine the values of quantum efficiency and then responsivity to solve problems
Vibration of crystals
These are the notes of vibration of crystals with microatomic basis; primitive basis of two atoms and it's optical mode
Heat capacity
Heat capacity: purity pf states in one dimension and purity of states in three dimension; Dibye model And in last we find out the heat capacity by using diagram
Debye T3 law
In this, Debye T3 law is discussed, einstein model of the density of states; then there are magnetic properties of matter And lurnor theorem
Paramagnetism and Ferromagnetism
These are the notes of Paramagnetism and Ferromagnetism and in the last, there are ferromagnetic domains
SUPERCONDUCTIVITY BY DR PAUL
Superconductivity is the set of physical properties observed in certain materials, wherein electrical resistance vanishes and from which magnetic flux fields are expelled. Any material exhibiting these properties is a superconductor. Unlike an ordinary metallic conductor, whose resistance decreases gradually as its temperature is lowered even down to near absolute zero, a superconductor has a characteristic critical temperature below which the resistance drops abruptly to zero. An electric current through a loop of superconducting wire can persist indefinitely with no power source.
