Rhombohedral Boron Nitride for Deep UV Nonlinear Spectroscopy
Seung Tae KimKyung Hee University, Seoul, Republic of Korea _______________________________________ Rhombohedral boron nitride (rBN) is a polytype of boron nitride with a rhombohedral crystal structure, characterized by layer sliding and inversion symmetry breaking. These structural properties enhance its nonlinear optical response, making rBN highly efficient in second harmonic generation (SHG). In this study, we investigate…
