Abstract: GRAPHENE MADE OF SP2 CARBON ATOMS AND ARRANGED IN HEXAGONAL LATTICE STRUCTURE, HAS ATTRACTED INTENSE ATTENTION OF RESEARCHERS FROM VARIOUS FIELDS. HOWEVER, THERE ARE SOME UNEXPLOITED ASPECTS OF GRAPHENE AND SEVERAL OBSTACLES IN ITS APPLICATIONS. IN THIS THESIS, WE MAINLY AIM TO SOLVE SEVERAL ELECTRONIC BOTTLENECK ISSUES ABOUT GRAPHENE. FIRST, A NOVEL TECHNIQUE WAS DEVELOPED TO PROBE THE VERTICAL CONDUCTIVITY OF STACKED GRAPHENE FILMS AND AN EFFECTIVE METHOD WAS EXPLOITED TO IMPROVE RELATIVELY POOR PLANE-TO-PLANE CONDUCTIVITY. SECONDLY, CONDUCTIVITY OF GRAPHENE FILMS IS REPORTED TO BE REDUCED BY CHARGED IMPURITY CENTERS AND OPTICAL PHONON SCATTERING FROM SUPPORTING SUBSTRATES. TO THIS END, A FACILE WAY TO MINIMIZE THE NEGATIVE EFFECT FROM THE UNDERLYING SUBSTRATE IS REPORTED HERE. BESIDE THESE, GRAPHENE INTERLAYER TO REDUCE BUILT-UP SCHOTTKY BARRIER BETWEEN WSE2 AND METAL ELECTRODE AND LARGE AREA BUCKLING-DELAMINATED PERIODIC HEXAGONAL PATTERN ON NANOCRYSTALLINE GRAPHITIC FILMS ARE ALSO
