Electronic structure of transition metal dichalcogenides under strain
(University of Missouri--Columbia, 2023)[EMBARGOED UNTIL 5/1/2024] The broken inversion symmetry in transition metal dichalcogenides(TMD) generates special orbital characters at the valley points in the Brillouin zone, which leads to various interesting phenomena ... -
Elucidation of quantum magnetic dynamics in semi-classical honeycomb lattice
(University of Missouri--Columbia, 2023)[EMBARGOED UNTIL 12/1/2024] The artificial spin ice systems are essentially arrays of single domain nanomagnets with specifically designed patterns, e.g. squares, honeycombs, etc. As a natural extension of the classical ... -
Exploring polymer dielectrics for donor-acceptor and small molecule based transistors and voltage inverters
(University of Missouri--Columbia, 2023)Organic semiconductor devices have gained much attention over the past several decades. Solution processability of polymer materials lends itself towards the realization of flexible, wearable electronic devices, owing to ... -
An investigation of the single-molecule biophysics of membrane systems with atomic force microscopy
(University of Missouri--Columbia, 2022)Cell membranes define the boundary of the fundamental unit of all organisms. They maintain the biochemical gradients of the cell and are carefully regulated by various membrane proteins and factors. Understanding of these ... -
Magnetic charge correlation and quantum disorder in honeycomb spin ice systems
(University of Missouri--Columbia, 2022)The artificial spin ice system consists of islands comprised of nanomagnets arranged in desired lattice structures, including squares, triangles, and honeycombs. These nanomagnets can also be arranged in an aperiodic lattice ... -
Nonlinear optical probes for organic field effect transistors and halide perovskites
(University of Missouri--Columbia, 2023)As the field of semiconductors is booming at an exponential rate, surpassing popular industry predictions like Moore's law, small molecule and polymer based semiconductors such as organic and hybrid (organic-inorganic) ... -
Photoemission spectroscopy and first-principles studies of two-dimensional Dirac and Weyl materials
(University of Missouri--Columbia, 2022)Two-dimensional (2D) materials have attracted tremendous research interest since the breakthrough of graphene. As the nature of the low dimension, 2D materials are thin, flexible, and easy for fabrication. More interestingly, ... -
Predicting RNA secondary structures using physics-based modeling and evolutionary inferences
(University of Missouri--Columbia, 2022)Ribonucleic acid (RNA) molecules are critical to gene expression and regulation at the level of transcription, splicing, translation, and catalysis of biochemical reactions. In order to understand RNA function, we need to ... -
Quantifying structural disorder in bulk hydrogenated graphene using x-ray and neutron diffraction
(University of Missouri--Columbia, 2022)Functionalization of graphene's two-dimensional sheets can be used to modify graphene's physical properties, such as changing its conductivity or inducing ferromagnetism, which is of broad interest for a myriad of applications. ...
