New Insights into Refractive Indices and Birefringence of Undoped and MgO-Doped Lithium Niobate Crystals at High Temperatures
Nina Hong, Jiarong R. Cui, Hyun Jung Kim +2
The lithium niobate single crystal is a well-known optical material that has been employed in a wide range of photonic applications. To realize further applications of the crystal,…
High-Efficiency Multilevel Phase Lenses with Nanostructures on Polyimide Membranes
Leslie Howe, Tharindu D. Rajapaksha, Kalani H. Ellepola +7
The emergence of planar meta-lenses on flexible materials has profoundly impacted the long-standing perception of diffractive optics. Despite their advantages, these lenses still f…
Interfacial Layers between Ion and Water Detected by Terahertz Spectroscopy
Abhishek K. Singh, Luan C. Doan, Djamila Lou +2
Dynamic fluctuations in hydrogen-bond network of water occur from femto- to nano-second timescale and provides insights into structural/dynamical aspects of water at ion-water inte…
Correlation between Macroscopic and Microscopic Relaxation Dynamics of Water: Evidence for Two Liquid Forms
Nguyen Q. Vinh, Luan C. Doan, Ngoc L. H. Hoang +2
Water is vital for life, and without it biomolecules and cells cannot maintain their structures and functions. The remarkable properties of water originate from its ability to form…
Effect of High-k Dielectric Layer on 1/f Noise Behavior in Graphene Field-Effect Transistors
Yifei Wang, Vinh X. Ho, Zachary. N. Henschel +2
We report the 1/f noise characteristics at low-frequency in graphene field-effect transistors that utilized a high-k dielectric tantalum oxide encapsulated layer (a few nanometers…
Insights into Hydration Dynamics and Cooperative Interactions in Glycerol-Water Mixtures by Terahertz Dielectric Spectroscopy
Ali Charkhesht, Djamila Lou, Ben Sindle +3
We report relaxation dynamics of glycerol-water mixtures as probed by megahertz-to-terahertz dielectric spectroscopy in a frequency range from 50 MHz to 0.5 THz at room temperature…
High-Precision Megahertz-to-Terahertz Dielectric Spectroscopy of Protein Collective Motions and Hydration Dynamics
Ali Charkhesht, Chola K. Regmi, Katie R. Mitchell-Koch +2
The low-frequency collective vibrational modes in proteins as well as the protein-water interface have been suggested as dominant factors controlling the efficiency of biochemical…
