This volume focuses on state-of-the-art terahertz spectroscopic techniques and important recent applications. It describes methods used for time-domain terahertz spectroscopic measurements, such as the generation and detection of terahertz radiation, the determination of optical constants, and the use of femtosecond lasers. The book also explores applications in physics and materials science, including carrier processes in semiconductor materials, superconductors, novel electronic materials, and semiconductor nanostructures. The final section reviews applications in chemistry and biomedicine,...
