Abstract
This thesis details an investigation into two regimes of charge transport where the behavior of the charge carriers is determined by quantum mechanical effects. An educational laboratory apparatus has been created to investigate small length scales comparable to the de Broglie wavelength of the electron, and display occurrences of quantized electrical conductance in mechanically controlled break junctions. An experiment using electron spin in ferromagnetic materials has been used to demonstrate effects corresponding to Giant Magnetoresistance in a bilayer system. These experiments provide a window into the effect of quantum mechanics on charge transport phenomena. This paper also presents information on equipment development and design, as well as directions for future research.
