Graphene: synthesis, transfer, characterization and growth mechanisms

Keywords: Chemical vapor deposition, chemistry, materials science, electronics, 2D materials

Recommendation: This program is designed for students interested in chemistry or Electrical Engineering.

Abstract:

Graphene has emerged as the most popular topic in the active research field since graphene's discovery in 2004 by Andrei Geim and Kostya Novoselov. Since then, graphene research has exponentially accelerated because of its extraordinary properties, which have attracted the interest of researchers all over the world. For example, among the key properties are its thermal conductivity, electrical conductivity, optical trans- parency, and mechanical properties. These remarkable properties of graphene show its promise for ap- plications in different industries including optical electronics, photovoltaic systems and others. However, the large-scale production and transfer method onto target substrates of monolayer graphene for commercial and industrial applications are still under study in the improvement stage. Therefore, this one-month program presents the state-of-the-art research activities and latest advancement in the synthesis of graphene using var- ious carbon precursors including solid, liquid and gas carbon feedstocks. The characterization methods will also be critically discussed in this program. In addition, the advancement in the transfer methods onto target substrates for achieving clean and high-quality transferred graphene will be covered. Furthermore, the cur- rent growth mechanisms of single and multilayer graphene will also be discussed.

Two Dimensional Materials for Electronic Applications

Keywords: Electrical engineering, physics, nanomaterials, nanoelectronics, graphene

Recommendation: This program is designed for students interested in Electrical Engineering, Physics and fundamental electronic components used in our electronic gadgets such as cell phones or computers.

Abstract:

Silicon-based integrated circuits are the major driving force behind the multi-billion dollar electronics indus- try. In the past 60 years, miniaturization of silicon devices and introduction of performance boosters such as strain, high-κ gate dielectrics and metal gates have been successful approaches in satisfying the insatiable demand for higher performance and lower power consumption in electronic systems. Nevertheless, the per- formance and scaling of conventional silicon devices are moving towards their scientific and technological limits, especially for sub-5 nm metal-oxide-semiconductor field effect transistor, thereby driving the elec- tronics industry's quest for new materials. The current International Technology Roadmap for Semiconduc- tors, which assesses the technology requisites for the next-generation semiconductor devices, has prominent- ly featured two-dimensional (2D) materials (e.g. graphene and MoS2) as potential candidates to replace sili- con as mainstream electronic materials.

Since the successful isolation and first electrical characterization of graphene in 2004, 2D materials have re- ceived tremendous attention from not only physicists and chemists, but also from electronic device and bio- medical engineers, due to their unique physical properties. The significance of the breakthrough by the pi- oneers of 2D materials research, Geim and Novoselov, is evidenced by the award of Nobel Prize in physics in an unusually short period of just 6 years (2010).

This program will explain the basis of electrical and optical properties of 2D materials including semicon- ductors, metals, organics and insulators, and will show how devices are built to take advantage of those properties. It is illustrated with a wide range of devices, placing a strong emphasis on new and emerging technologies. Applications covered include diodes, transistors, memristor memories, photodetectors, solar cells (photovoltaics), displays, light emitting diodes, photonic devices, and flexible electronics. At the end of the program, students are encouraged to choose one application and write a 5 page review report.
