A p-n junction is A material, which allows amplification of current. A p-doped and n-doped material, which are joined by a wire. A material, which allows conduction of current similar to a metal. A material which is p and n-doped throughout. A material with p and n-doped material on either side. A material with a temperature independent resistance.
The chemical potential along a p-n junction is: The same value across the entire junction, since it only depends on the lattice. A different value across the entire junction, in order to eliminate net particle migration. Closer to the valence band in the n-type region. Closer to the conduction band in the n-type region. O Higher in the p-doped region. O Higher in the n-doped region.
If we want to extract the probability of finding a particle between points a and b, we must: differentiate the absolute value of the normalised wave function. O find the area of the normalised wave function between a and b. O integrate the absolute value of the normalised wave function between a and b. integrate the normalised wave function over all space. O integrate the absolute value of the normalised wave function over all space. O subtract the wave function at a from the wave function at b.
The valence electrons in a crystal of N ions occupy the energy states as follows a. There are N quantum states available for the electrons. b. There are 2N quantum states available if spin is taken into account. An even number of valence electrons donated by the lattice ions will occupy the highest energy band completely. d. The electrons will occupy the conduction band first. An odd number of valence electrons donated by the lattice ions will occupy a band completely. f. An odd number of valence electrons donated by the lattice ions will occupy one band one to half capacity.
