Introduction to Spectroscopic Ellipsometry of Thin Film Materials Instrumentation, Data Analysis, and Applications

A one-of-a-kind text offering an introduction to the use of spectroscopic ellipsometry for novel material characterization

In Introduction to Spectroscopic Ellipsometry of Thin Film Materials: Instrumentation, Data Analysis and Applications, a team of eminent researchers delivers an incisive exploration of how the traditional experimental technique of spectroscopic ellipsometry is used to characterize the intrinsic properties of novel materials. The book focuses on the scientifically and technologically important two-dimensional transition metal dichalcogenides (2D-TMDs), magnetic oxides like manganite materials, and unconventional superconductors, including copper oxide systems.

The distinguished authors discuss the characterization of properties, like electronic structures, interfacial properties, and the consequent quasiparticle dynamics in novel quantum materials. Along with illustrative and specific case studies on how spectroscopic ellipsometry is used to study the optical and quasiparticle properties of novel systems, the book includes:

• Thorough introductions to the basic principles of spectroscopic ellipsometry and strongly correlated systems, including copper oxides and manganites
• Comprehensive explorations of two-dimensional transition metal dichalcogenides
• Practical discussions of single layer graphene systems and nickelate systems
• In-depth examinations of potential future developments and applications of spectroscopic ellipsometry

Perfect for master’s- and PhD-level students in physics and chemistry, Introduction to Spectroscopic Ellipsometry of Thin Film Materials will also earn a place in the libraries of those studying materials science seeking a one-stop reference for the applications of spectroscopic ellipsometry to novel developed materials.

Dr. Yin Xinmao, Research Fellow in Physics department in National University of Singapore and Singapore Synchrotron Light Source (2014-present). He completed his degrees of the bachelor and PhD in Zhejiang University in 2010 and National University in 2015, respectively. His expertise is in the field of condensed matter physics and optical spectroscopy, with primary strength in studying the electronic and spin structures of materials using optical spectroscopic techniques at different energy range. He specializes in studying materials such as 2D transition metal dichalcogenides, High-Tc superconducting cuprates, and colossal magnetoresistance manganites and their interfaces. He is expert in the various optical analysis techniques (ellipsometry, reflectivity, absorption, etc.) and the synchrotron-based spectroscopy (XAS, XMCD, XRD, XPS, ARPES etc.). Using these spectroscopic techniques, the underlying physical mechanism of macroscopic and microscopic properties governing superconductivity, ferromagnetism, phase transition, as well as spin changes, plasma and exciton excitations have been studied.
