Graphene materials having randomly distributed two-dimensional structural defects

Title: Graphene materials having randomly distributed two-dimensional structural defects

Graphene-based storage materials for high-power battery applications are provided. The storage materials are composed of vertical stacks of graphene sheets and have reduced resistance for Li ion transport. This reduced resistance is achieved by incorporating a random distribution of structural defects into the stacked graphene sheets, whereby the structural defects facilitate the diffusion of Li ions into the interior of the storage materials.

Local doping of two-dimensional materials

Patent Wong, Dillon ; Velasco, Jr, Jairo ; Ju, Long ; Kahn, Salman ; Lee, Juwon ; Germany, Chad E. ; Zettl, Alexander K. ; Wang, Feng ; Crommie, Michael F.

This disclosure provides systems, methods, and apparatus related to locally doping two-dimensional (2D) materials. In one aspect, an assembly including a substrate, a first insulator disposed on the substrate, a second insulator disposed on the first insulator, and a 2D material disposed on the second insulator is formed. A first voltage is applied between the 2D material and the substrate. With the first voltage applied between the 2D material and the substrate, a second voltage is applied between the 2D material and a probe positioned proximate the 2D material. The second voltage between the 2D material and the probe ismore »« less

Patent Geohegan, David B. ; Rouleau, Christopher M. ; Wang, Kai ; Xiao, Kai ; Lin, Ming-Wei ; Puretzky, Alexander A. ; Mahjouri-Samani, Masoud

Methods, articles of manufacture and systems for creating new nanoscale two dimensional materials comprising designed arrays of lateral or vertical heterojunctions may be fabricated by first lithographically masking a 2D material. Exposed, or unmasked, regions of the 2D material may be converted to a different composition of matter to form lateral or vertical heterojunctions according to the patterned mask. PLD and high kinetic energy impingement of atoms may replace or add atoms in the exposed regions, and a plurality of the exposed regions may be converted concurrently. The process may be repeated one or more times on either side ofmore »« less
