| dc.description.abstract | En años recientes, después que fue posible separar la capa de grafeno de una estructura grafítica, un gran número de trabajos ha sido dedicado a estudiar este sistema debido a las propiedades no peculiares encontradas en este material [28, 29, 27, 6, 9, 2, 19, 12, 10, 13, 11, 40, 39, 8, 18]. La estructura característica del grafeno, en la cual las bandas de valencia y de conducción se tocan en dos puntos no equivalentes en la esquina de la primera zona de Brillouin, como consecuencia de su red en forma de pánel de abejas, hace a este material ópticamente transparente al igual que altamente buen conductor [26, 4] (ver Figura 1.1). Por lo anterior, las excitaciones de baja energía en grafeno poseen un espectro de dispersión lineal similar a los fotones en la radiación electromagnética, lo cual afecta de manera radical las propiedades de transporte en este sistema. En particular, las propiedades ópticas y eléctricas en grafeno bajo la acción de campos alternos intensos hansido objeto de muchas investigaciones, encontrandose que la radiación ac cambia de manera sorpresiva la estructura energética y, consecuentemente, la densidad de estados de este sistema [7, 25]. En este sentido, una variedad de fenómenos han sido predichos para ser observados en grafeno, como por ejemplo el efecto Hall fotovoltáico [30], las corriente valle-polarizadas [33], etc.. | spa |
