description: Disordered semiconductors, including poly-crystalline and amorphous semiconductors, have unique properties that can be attributed to the disorder present within their atomic structure. While the distribution of electronic states associated with a defect-free crystalline semiconductor terminates abruptly at the band edges, in a disordered semiconductor, electronic states encroach into this otherwise empty gap region. This encroachment of the electronic states into the band gap region of a disordered semiconductor can be credited for many of its unique properties. Unfortunately, due to its random nature, the quantitative characterization of the disorder that is present within a disordered semiconductor has proven a difficult task to grapple with. The distribution of potential fluctuations found within such a material has a direct impact on the distribution of electronic states within a disordered semiconductor. The aim of this thesis is to characterize this distribution of potential fluctuations. In particular, I use a Monte Carlo approach, where simulations, replicating the random nature of the defects found within a disordered semiconductor, are performed a large number of times in order to obtain the distribution of potential fluctuations associated with such a semiconductor. With the distribution of potential fluctuations evaluated, the impact on the corresponding distribution of electronic states will be probed.

While the distribution of elec-tronic states associated with a defect-free crystalline semiconductor termi-nates abruptly at the band edges, in a disordered semiconductor, electronicstates encroach into this otherwise empty gap region. This encroachment ofthe electronic states into the band gap region of a disordered semiconduc-tor can be credited for many of its unique properties.
