      B is usually given in units of cm 1, and in order to end up with these units, the speed of light in this equation, c, needs to be in cm s 1 rather than ms 1. Using B in cm 1 will yield the energy in the same units. [Note: cm 1 are common units in spectroscopy for historical reasons, even though they are non-SI. Units of

Under the influence of a bias voltage these carriers move through the material and induce a current in the external circuit. 3. For each electron-hole pair created, the result is an electron flowing in the circuit.
