WHITE PAPER

Lake Shore Cryotronics, Inc. - Characterization to the Extremes: Terahertz materials characterization at cryogenic temperatures and high magnetic fields

Characterization to the Extremes: Terahertz materials characterization at cryogenic temperatures and high magnetic fields
Lake Shore Cryotronics, Inc.

In continuing pursuit of improved performance, higher processing speed, and more compact packaging, researchers spend considerable time identifying and characterizing novel and previously unexplored materials. Recently, the terahertz frequency range has emerged as a new frontier for materials science, helping to map out this unknown territory. This paper explores how THz energy can be used to gain insights into material properties, particularly under variable or extreme temperatures and magnetic fields.
