人工复合纳米级分子的光学双稳性:面向纳米级的所有光学处理
Optical bistability in artificial composite nanoscale molecules: Towards all optical processing at the nanoscale
摘要:
从理论上研究了由半导体量子点和贵金属纳米颗粒组成的人工复合纳米分子的光学响应。我们考虑了由Au粒子和CdSe或CdSe/ZnSe量子点组成的系统,并预测了其响应的光学双稳态和滞后,这表明了各种应用,特别是全光处理和光存储。
英文摘要:
Optical response of artificial composite nanoscale molecules comprising a closely spaced noble metal nanoparticle and a semiconductor quantum dot have been studied theoretically. We consider a system composed of an Au particle and CdSe or CdSe/ZnSe quantum dot and predict optical bistability and hysteresis in its response, which suggests various applications, in particular, all-optical processing and optical memory.
