Study of photorefractive memory using gallium nitride crystals

体全息存储器（VHM）因其存储容量大、传输速率快等优点，有望成为下一代光学数据存储系统。在本研究中，我们研究了宽禁带氮化晶体作为一种新的VHM记录材料的记录性能。本研究揭示的录音模型对今后录音材料的开发和完善具有重要意义。

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.
