1. Emissão de elétrons por efeito de campo em dispositivos de grafeno
Since graphene was first isolated in 2004 by the micromechanical exfoliation of graphite, many research groups focused their works in studying the properties of this material. Graphene is a strictly bidimensional system very resilient to mechanical tension which presents high charge carriers mobilities, anomalous quantum hall effect observed even at room tem

2. Magneto-transporte no limite quantico em grafite e bismuto / Magnet transport in the quantum limit in graphite and bismuth
Esta tese é o resultado da investigação das propriedades elétricas e magnéticas de dois semimetais: bismuto (Bi) policristalino romboédrico e grafite pirolítica altamente orientada (HOPG). Inicialmente nós discutimos o efeito Hall no limite quântico, que acontece em amostras de grafite HOPG com certo grau de desordem e onde a desordem é reduzida. E

3. Graphite as a bose metal
Although a considerable amount of the research work has been done on graphite, its physical properties are still not well understood, and novel phenomena such as the magnetic-field-driven metal-insulator transition (MIT), the quantum Hall effect, ferromagnetic and superconducting correlations have recently been revealed. Theoretical analysis suggests that th
