Unveiling the delicate "hidden" interface conditions in WS2 flakes by advanced atomic force microscopy
Yanyan Geng, Chang Li, Shuo Mi +15
The delicate interfacial conditions and behaviors play critical roles in determining the valuable physical properties of two-dimensional materials and their heterostructures on sub…
Multi-level Optical Switching by Amorphization in Single- and Multi- Phase Change Material Structures
Simon Wredh, Yunzheng Wang, Joel K. W. Yang +1
The optical properties of phase-change materials (PCM) can be tuned to multiple levels by controlling the transition between their amorphous and crystalline phases. In multi-materi…
Low Thermal Conductivity Phase Change Memory Superlattices
Jing Ning, Xilin Zhou, Yunzheng Wang +6
Phase change memory devices are typically reset by melt-quenching a material to radically lower its electrical conductance. The high power and concomitantly high current density re…
Tunable wavefront control in the visible spectrum using low-loss chalcogenide phase change metasurfaces
Parikshit Moitra, Yunzheng Wang, Xinan Liang +6
All-dielectric metasurfaces provide unique solutions for advanced wavefront manipulation of light with complete control of amplitude and phase at sub-wavelength scales. One limitat…
Low energy switching of phase change materials using a 2D thermal boundary layer
Jing Ning, Yunzheng Wang, Ting Yu Teo +7
The switchable optical and electrical properties of phase change materials (PCMs) are finding new applications beyond data storage in reconfigurable photonic devices. However, high…
Tunable Mie Resonances in the Visible Spectrum
Li Lu, Zhaogang Dong, Febiana Tijiptoharsono +7
Dielectric optical nanoantennas play an important role in color displays, metasurface holograms, and wavefront shaping applications. They usually exploit Mie resonances as supporte…
A scheme for simulating multi-level phase change photonics materials
Yunzheng Wang, Jing Ning, Li Lu +2
Chalcogenide phase change materials (PCMs) have been extensively applied in data storage, and they are now being proposed for high resolution displays, holographic displays, reprog…
