Study of photorefractive memory using gallium nitride crystals

体全息存储器（VHM）因其存储容量大、传输速度快而被认为是下一代光存储系统。本研究以宽禁带氮化物晶体作为VHM的新型记录材料，研究其记录特性。本研究揭示的录音模式对今后录音材料的发展和完善具有重要的指导意义。

Volume holographic memory (VHM) has been expected to be a next-generation optical data storage system because of its large storage capacity and fast transfer rate. In this study, we investigated the recording properties in wide band-gap nitride crystals as a new recording material of VHM. Their recording models revealed in this study play an important role to develop and improve the recording material in future.
