摘要: Abstract We review the technique of ‘specific heat spectroscopy,’ Birge and Nagel. The technique, also called ‘3ω method’ in literature, is nonadiabatic; it based on thermal diffusion into a thick sample from thin metallic film that serves simultaneously as heater thermometer. Specific spectroscopy allows one to measure dynamic specific liquid or solid over frequency range exceeding 6 decades, conductivity more limited range. Designed study supercooled liquids near glass transition, has been used phase transitions biological systems.
