Abstract

The phase transition and the reversible optical and electrical switching that occur in chromogenic materials under the influence of external forces such as heat, light, and electric field are topics of enormous scientific interest. Transition Metal Oxide Thin Film–Based Chromogenics and Devices discusses experimental and theoretical developments in the field of chromogenics based on the transition metal oxide (TMO) thin films.

Understanding the relationship between the switching properties of TMO materials and their nanostructure is of paramount importance in developing efficient chromogenic devices. The tailoring of these switching behaviors is afforded detailed coverage in this book, alongside in-depth discussion of a range of chromogenic materials and devices, including photochromics, thermochromics, and electrochromics.

Transition Metal Oxide Thin Film–Based Chromogenics and Devices covers both the theoretical aspects of TMO thin film–based chromogenics and their engineering applications in device construction. Academics and professionals in the fields of materials science and optics will find this book to be a key resource, whether their focus is low-dimension materials, light-materials interactions, or device development.

  • Enables researchers to keep up with developments in thin film–based chromogenics
  • Provides detailed coverage of the switching mechanism of the various TMO thin films to assist readers in developing more efficient devices
  • Offers in-depth discussion of a range of chromogenic materials and devices, including thermochromics, photochromics, and electrochromics
