QUANTUM PHYSICS MCQ' QUESTIONS PLEASE HELP
Which statement about electrons in an intrinsic semiconductor is INCORRECT. They: O can jump from the valence into the conduction band. can jump to higher and lower levels within the conduction band. can acquire energy to jump within the valence band if the valence band is not completely filled. O cannot jump within the valence band at OK. can jump from the conduction into the valence band. O will more likely jump from the bottom of the valence band to the conduction band.
In a finite temperature bosonic system, the chemical potential has this property: O It behaves identically to a fermionic system. O It does not play a role. O It cannot become negative. O It can be adjusted to allow for a negative average number of particles in a single particle state. It is always lower than the lowest allowed energy. O An increase in temperature always accompanies an increase in chemical potential.
A bound state system in quantum mechanics O can contain wave functions going to infinity. has only a continuous spectrum. contains a particle whose kinetic energy is more than the potential energy at infinity. O imposes boundary conditions on the wave function. O has a discrete and continuous spectrum. O must have a completely symmetric potential in all directions.
