Three-dimensional imaging of threading dislocations in GaN crystals using two-photon excitation photoluminescence

“…This method has been developed as a bioscience imaging technology for visualizing in vivo living tissues. [20][21][22] In this method, the excitation wavelength is longer than the photoluminescence (PL) wavelength. The two-photon absorption process is different from the conventional absorption process, in which the excitation wavelength is shorter than the PL wavelength.…”
