Observation and investigation of graphite superlattice boundaries by scanning tunneling microscopy

Structural and electronic properties of grain boundaries in graphite: Planes of periodically distributed point defects

“…Observations of grain boundaries have been reported on the graphite surface with STM before [8][9][10][11] and recently also on few graphene layers grown on C face of SiC. 12 Periodic structures [9][10][11][12] and disordered regions 8 have been observed along grain boundaries. For a large-angle-tilt grain boundary evidence of possible presence of pentagon-heptagon pairs was shown.…”

Effects of the Superlattices on STM Imaging of Self-organized Substituted Alkyl Chain Monolayers on a Graphite Surface

“…16,19 Giant hexagonal periodic patterns with periodicities from a few to tens of nm, referred to as Moiré patterns, can extend over hundreds of nanometers. [20][21][22][23][24][25][26][27][28][29][30][31] These superperiodic patterns were previously attributed to misorientations in the surface layer with respect to the second layer of graphite, or to subsurface arrays of nanoscale defects.…”

Introduction

“…The improved quality is adequate for research experiments and industrial applications [41][42][43][44][45][46][47][48][49]. In addition, AAB stacking and intermediate bilayer configurations, with relative layer-layer shifts or twists, have also been found and are becoming interesting subjects [59][60][61][62][63][64][65][66][67]. Synthesized graphene is generally comprised of different kinds of domain due to the tiny difference between the total energies of the different configurations.…”
