Hint	Answer	% Correct
amount of energy a material can store per kelvin	heat capacity	100%
a quantum of energy	phonon	100%
union of electron and hole to return to a neutral state	recombination	100%
equivalent to a Wigner Seitz cell in reciprocal space	Brillouin zone	50%
any solid with a repeated structure	crystal	50%
apparent mass of a particle when responding to forces	effective mass	50%
the highest occupied electron state at absolute zero temperature	fermi energy	50%
empty state in valence band due to excitation of an electron into the conduction band	hole	50%
a pair of p-n junctions	transistor	50%
the eigenfunction of the wave equation for a periodic potential is the product of a plane wave and the potential that has the periodicity of the crystal	bloch's theorem	0%
ability of a charge carrier to move through a material in response to an electric field	carrier mobility	0%
electrons and holes recombine with each other resulting in no net charge carriers	depletion region	0%
majority carrier diffuse into minority region and recombine with majority carriers	diffusion current	0%
adding/removing an electron from a semi conductor	doping	0%
thermally generated minority carriers drift into the majority region, swept by built in e field	drift current	0%
surface in reciprocal space that separates filled and unfilled states at absolute zero	fermi surface	0%
in a filled band as many electrons move to the left as to the right	insulator	0%
a vector that describes the translational periodicity of a lattice	lattice vector	0%
total relaxation times is dependent on different sources (defects, impurities and phonons)	Matthiessen rule	0%
incomplete band filling creates a Fermi surface, electric field shifts Fermi surface so not as many electrons are moving to the left as the right	metal	0%
total linear momentum conserved, no heat resistance	normal process	0%
no 2 electrons can share the same set of quantum numbers	pauli exclusion principle	0%
one atomic species is swapped for another	substitution	0%
requires high energy phonons, direction of total linear momentum is reversed, responsible for heat resistance	umklapp process	0%
assuming scattering times are the same, 2 transport processes are only different by heat capacity and charge	wiedemann-franz law	0%
region about a lattice point that is closer to that lattice point than any other	Wigner seitz cell	0%
distance between fermi level and vacuum level	work function	0%
