Frequency-domain energy transport state-resolved Raman for measuring the thermal conductivity of suspended nm-thick MoSe2

Temperature-dependent Raman properties calibration and laser absorption evaluation are two significant sources of error in measurement of nm-thick materials thermal conductivity based on steady state Raman spectroscopy. A new Raman probing technique, frequency-domain energy transport state-resolved Raman (FET-Raman), is developed to resolve these issues and improve the measurement precision significantly. The FET-Raman uses a steady-state laser...
