The strong interaction between free electrons and longitudinal-optical phonons gives rise to a 42 meV-period modulation of the efficiency of carrier collection into the well and of the corresponding collection time. The energy position of the electronic level driving the capture into the well has ...

Spatially resolved vibrational mapping of nanostructures is indispensable to the development and understanding of thermal nanodevices1, modulation of thermal transport2 and novel nanostructured thermoelectric materials3–5. Through the engineering of com
We observe that the Raman intensity depends on the thickness and the excitation energy due to the combined effects of interference and resonance from the band-structure modulation. Furthermore, confined acoustic phonon modes in the ultrathin Si NMs were observed in ultralow-frequency Raman spectra,...
