Energy-Efficient Non-Volatile Photonic Switching via Composition-Engineered Sn-Doped GST
Xingyu Zhang, Daniel Vaz, Chi-Yi Kao +5
Integrated phase-change photonics allows non-volatile optical switching with no static power draw, but the electrical energy needed to reversibly switch the material's state limits…

Counterdirectional Exciton and Trion Motion in Applied Electric Field
Daniel Vaz, Yuanjun Guan, Qiaochu Wan +13
Charged excitonic complexes are central to the optoelectronic and many-body properties of semiconductors, yet their real-space transport dynamics remain largely unexplored. Here, w…
