“…Figure 10 compares the Si-Si Raman peak position and FWHM in Si/Ge NW HJs with the theoretically predicted and experimentally confirmed temperature dependencies of that in bulk c-Si. 46,47 The Si-Si Raman peak position in Si/Ge NW HJs is in full agreement with the bulk c-Si Raman temperature dependence calculated by using Ref. 46 ( Fig.…”

“…27 On considering the Raman measurements, we anticipate that under the applied laser excitation intensity of 10 2 -10 3 W/ cm 2 the sample temperature increases, and such temperature increase can be detected by monitoring the Raman peak wavenumber and FWHM temperature dependencies. 46,47 Generally, as temperature increases, the Raman peak shifts toward lower wavenumber due to thermal expansion and changes in the self-energy of the vibrational mode. 46 At the same time, the Raman peak FWHM increases, mainly due to energy relaxation processes (i.e., the decay of the Raman phonon into various optical/acoustical phonons, etc.).…”

“…This is completely analogous to that used for the calibration of the motional thermometry of ions (atoms) trapped in electrical (optical) traps [25][26][27][28]. Additionally, these scattering processes have an underlying physics similar to the bulk nonlinear Raman-scattering processes used in the spectroscopic analysis of crystals [29,30], where an ensemble of vibrational degrees of freedom internal to the molecular structure of the system interacts with incident light. Typically, in these nonlinear optics experiments, photon counters are used to keep track of the (anti-)Stokes photons.…”

“…There are however interesting opportunities when the polarization splitting is precisely two times the mechanical frequency. For example, an alternative method for side-band thermometry [29][30][31][32][33], which is the optomechanical equivalent to Ramanratio thermometry in cold atoms [34] and solids [35], is possible. In Fig.…”
