The present thesis contains research in two related avenues of theoretical physics. We first present supersymmetric low-energy background field solutions of D-brane bound states in type IIA and type IIB theories. We derive new solutions describing two parallel D-branes which have a difference in dimension of two, using a procedure which involves rotations and T-duality transformations. We also present original supersymmetric background field solutions in which the D-branes are at angles to each other. These solutions are distinguished by the presence of an Hermitian metric on the internal compact space, and again, T-duality transformations are used to build more supersymmetric configurations of D-branes at angles. The second part of the research presents a two-dimensional model of gravity which possesses black hole solutions. We study Hawking radiation and we explicitly show that it has a mass-dependent temperature. Semiclassical issues are also investigated.
