Blaschke Product Neural Networks (BPNN): A Physics-Infused Neural Network for Phase Retrieval of Meromorphic Functions
Juncheng Dong, Simiao Ren, Yang Deng +5
Numerous physical systems are described by ordinary or partial differential equations whose solutions are given by holomorphic or meromorphic functions in the complex domain. In ma…
Infrared nano-spectroscopy of ferroelastic domain walls in hybrid improper ferroelectric CaTiO
K. A. Smith, E. A. Nowadnick, S. Fan +14
Ferroic materials are well known to exhibit heterogeneity in the form of domain walls. Understanding the properties of these boundaries is crucial for controlling functionality wit…
Hybrid tip-enhanced nano-spectroscopy and -imaging of monolayer WSe2 with local strain control
Kyoung-Duck Park, Omar Khatib, Vasily Kravtsov +3
Many classes of two-dimensional (2D) materials have emerged as potential platforms for novel electronic and optical devices. However, the physical properties are strongly influence…
Graphene-Based Platform for Infrared Near-Field Nanospectroscopy of Water and Biological Materials in an Aqueous Environment
Omar Khatib, Joshua D. Wood, Alexander S. McLeod +12
Scattering scanning near-field optical microscopy (s-SNOM) has emerged as a powerful nanoscale spectroscopic tool capable of characterizing individual biomacromolecules and molecul…
Gap states in insulating LaMnPOF (x = 0 - 0.3)
J. W. Simonson, K. Post, C. Marques +4
Infrared transmission and electrical resistivity measurements reveal that single crystals of LaMnPOF (x 0.28) are insulating. The optical gap obtained from tra…
Infrared signatures of high carrier densities induced in semiconducting poly(3-hexylthiophene) by fluorinated organosilane molecules
Omar Khatib, Bumsu Lee, Jonathan D. Yuen +5
We report on infrared (IR) absorption and dc electrical measurements of thin films of poly(3-hexylthiophene) (P3HT) that have been modified by a fluoroalkyl trichlorosilane (FTS).…
Reconfigurable Gradient Index using VO2 Memory Metamaterials
M. D. Goldflam, T. Driscoll, B. Chapler +9
We demonstrate tuning of a metamaterial device that incorporates a form of spatial gradient control. Electrical tuning of the metamaterial is achieved through a vanadium dioxide la…
