semi-conductor T/F problems

True or False: D-orbit can hold maximum 6 electrons

False

True or False: The momentum of a photon is the ratio of its energy to the speed of light

True

True or False: The blackbody spectrum depends only on temperature

True

True or False: Electron has both particle and wave like nature

True

True or False: According to the Pauli exclusion principle the joining of atoms to form a crystal does not alter the total number of quantum states

True

True or False: The probability of finding an electron is 50% at fermi energy level

True

True or False: The kinetic energy of electrons is inversely proportional to momentum

False

True or False: Incase of indirect bandgap change in momentum is not necessary

False

True or False: The probability distribution of finding an electron in a free space is a constant

True

True or False: At thermal energy there is always a finite number of electrons and holes in conduction band and valence band respectively

True

True or False: Higher curvature materials are useful for high-speed electronic devices

True

True or False: At the equilibrium interatomic distance, there is a band of allowed energies, but within the allowed band, the energies are at discrete levels

True

what is thermal energy?

Thermal energy (kBT = 0.0259 eV at 300K) is the lattice vibration energy that excites electrons across the bandgap and dictates carrier distribution in energy bands"

Write statement of Heisenberg Uncertainty principle

The Heisenberg Uncertainty principle states that position and momentum cannot be measured simultaneously with absolute precision.
