For job seekers: Surface Chemist

The surface scientist works at the interface of resident SPM/XPS, synthetic chemistry, and theoretical groups in the preparation, deposition, and characterization of both small molecules (organics, conjugated species, small aromatic systems) and macromolecules (CNTs, graphene) on (primarily) passivated and reactive silicon surfaces. Central to the surface science work is the characterization of molecular geometry, molecular mobility, and deposition behavior at solid-vacuum interfaces, the study, and characterization of stable and reactive products generated by the AFM/STM group using probe-based techniques, the use of vapor-phase techniques in the assistance of preparation of organic monolayers onto surfaces, and the application of physical models for providing feedback and validation to theoreticians developing reactive force field and quantum chemical methods. The surface scientist will also be responsible for purchasing and coordination efforts with laboratory and facility managers in the acquisition and maintenance of new UHV equipment.

Description

Defects in Two-Dimensional Materials addresses the fundamental physics and chemistry of defects in 2D materials and their effects on physical, electrical and optical properties. The book explores 2D materials such as graphene, hexagonal boron nitride (h-BN) and transition metal dichalcogenides (TMD). This knowledge will enable scientists and engineers to tune 2D materials properties to meet specific application requirements. The book reviews the techniques to characterize 2D material defects and compares the defects present in the various 2D materials (e.g. graphene, h-BN, TMDs, phosphorene, silicene, etc.).

As two-dimensional materials research and development is a fast-growing field that could lead to many industrial applications, the primary objective of this book is to review, discuss and present opportunities in controlling defects in these materials to improve device performance in general or use the defects in a controlled way for novel applications.

Key Features
Presents the theory, physics, and chemistry of 2D materials
Catalogues defects of 2D materials and their impacts on materials properties and performance
Reviews methods to characterize, control and engineer defects in 2D materials

Readership
