Win the Materials Race: Extract New Information (Quickly) with Temperature-Dependent Raman and PL

This webinar, sponsored by Montana Instruments, will introduce techniques to improve the efficiency and control of variable temperature measurements in a closed-cycle (cryogen-free) system, including considerations for improved collection efficiency, thermo-mechanical stability, sample and optical drift, and rapid temperature control.

Raman micro-spectroscopy is well suited for studying a variety of properties in low dimensional materials. Many interesting phenomena emerge at cryogenic temperatures, and often, additional or new information about a sample can be obtained with temperature-dependent measurements.

Optical investigations of materials at variable temperatures, especially below 80K, can become complicated and time-consuming due to restricted sample spaces, limited optical access, and difficulties with thermal management, all of which contribute to poor efficiency and low experimental throughput. These difficulties are exacerbated when using expensive liquid helium (flow) cryostats. This webinar, sponsored by Montana Instruments, will introduce techniques to improve the efficiency and control of variable temperature measurements in a closed-cycle (cryogen-free) system, including considerations for improved collection efficiency, thermo-mechanical stability, sample and optical drift, and rapid temperature control.

Experimental Raman and photoluminescence (PL) data from 4K – 600K will be presented, along with a review of the measurement setup and parameters. Materials studied include transition metal dichalcogenides (MoS2 and WSe2) as well as single and double-layer graphene.
