Elimination of photothermal effect on nano-mechanical resonator consisting of optically transparent h-BN sheet

Two-dimensional atomic layer materials with optically transparent materials such as h-BN are expected to be high performance nano-electro-mechanical resonators (NEMR). Elimination of the photothermal effect is very crucial for accurate force sensing using NEMR. Thus, the optically transparent material such as h-BN is one of strong candidates for this purpose. Here, we investigate the photothermal effect on the mechanical resonance properties of the h-BN-NEMR driven by electrostatically using the dielectric effect.
