David Páez, Laura Rodríguez, Júlia TomàsResponsable: Joaquim Puigdollers The first objective of this work consisted of measuring the transfer curve at different temperatures of Ntrimethyltriindole from an organic transistor which substrate was made of that material and, analyzing these data, calculate the density of states of N-trimethyltriindole. Unfortunately, it could not be achieved due to the fact that the data collected was not good enough in order to be analyzed. That is the reason why in this work the density of states of the pentacene is calculated from the electrical characteristics of a thin-film transistor measured at different temperatures. 2015/2016
