USING the 2536.5 radiation of the mercury arc as the exciter and a Hilger Intermediate quartz spectrograph, the faint second-order Raman spectrum of diamond was first successfully recorded by me 1.

Characterization techniques such as Raman spectroscopy and ab initio calculations have also been employed to study natural occurrences of diamond and lonsdaleite, a hexagonal form of diamond.

Raman thermography measures the temperature of tiny semiconductor device structures ... and also heat transfer across interfaces inside the semiconductor devices, including the impact of material ...
