摘要：

In this theoretical work, we study the Raman spectra of double-walled boron nitride nanotubes (DBNNTs) as a function of their diameters, chiralities, and lengths. Calculations are performed using the spectral moments method coupled to the bond polarizability model. This original approach allows us to consider not only infinite tubes as usual in most theoretical models but also tubes with finite lengths. We provide benchmark theoretical data to estimate the diameter and length of DBNNTs using Raman measurements.
