In this work we study the influence on electronic properties of carbon in its diamond crystallographic structure as the pressure is increased. The Density Functional Theory (DFT) is used to calculate the base state of carbon. Some structural characteristics in function of pressure are determined, such as: the cohesion energy, lattice constant and energy gap. Additionally we presented the band structure calculation, in order to obtain evidence about the semiconductor character of this material and the presence of an indirect band gap.
