Anisotropic electronic, mechanical, and optical properties of monolayer WTe2
(American Institute of Physics Inc., 2016)Using first-principles calculations, we investigate the electronic, mechanical, and optical properties of monolayer WTe2. Atomic structure and ground state properties of monolayer WTe2 (Td phase) are anisotropic which are ... -
Attributed relational graphs for cell nucleus segmentation in fluorescence microscopy images
(IEEE, 2013)More rapid and accurate high-throughput screening in molecular cellular biology research has become possible with the development of automated microscopy imaging, for which cell nucleus segmentation commonly constitutes ... -
Characterization and stability of Janus TiXY (X/Y = S, Se, and Te) monolayers
(American Chemical Society, 2019)The realization of Janus MoSSe monolayers has brought two-dimensional (2D), ternary transition metal dichalcogenides (TMDs) into focus. The addition of a third element can lead to superior properties, hence extensive ... -
Effective mass of electron in monolayer graphene: Electron-phonon interaction
(AIP Publishing LLC, 2013-01-25)Shubnikov-de Haas (SdH) and Hall effect measurements performed in a temperature range between 1.8 and 275 K, at an electric field up to 35 kV m -1 and magnetic fields up to 11 T, have been used to investigate the electronic ... -
Enhanced interactions of amino acids and nucleic acid bases with bare black phosphorene monolayer mediated by coadsorbed species
(American Chemical Society, 2019)In this paper, we characterize amino acids and nucleic acid bases (nucleobases), such as glutamine, histidine, tyrosine, adenine, guanine, cytosine, and thymine, and examine their interaction with bare, as well as with ... -
Finite temperature studies of Te adsorption on Si(0 0 1)
(Elsevier, 2002)We perform first principles density functional calculations to investigate the adsorption of Te on the Si(0 0 1) surface from low coverage up to a monolayer coverage. At low coverage, a Te atom is adsorbed on top of the ... -
Hybridization of fano and vibrational resonances in surface-enhanced infrared absorption spectroscopy of streptavidin monolayers on metamaterial substrates
(2014)We present spectral hybridization of organic and inorganic resonant materials and related bio-sensing mechanism. We utilized a bound protein (streptavidin) and a Fano-resonant metasurface to illustrate the concept. The ... -
Infrared absorption spectroscopy of monolayers with thin film interference coatings
(Optical Society of America, 2017)We report high performance Infrared spectroscopy platforms based on interference coatings on metal using CaF2 dielectric films and Ge2Sb2Te5 (GST) phase-change films. IR vibrational bands of proteins and organic monolayers ... -
Mechanical and electrical monitoring in the dynamics of twisted phosphorene nanoflakes on 2D monolayers
(American Chemical Society, 2019)We investigated the rotational and translational dynamics of hydrogen-passivated, black phosphorene and blue phosphorene nanoflakes of diverse size and geometry anchored to graphene, black phosphorene, blue phosphorene, ... -
Mo2C as a high capacity anode material: a first-principles study
(Royal Society of Chemistry, 2016)The adsorption and diffusion of Li, Na, K and Ca atoms on a Mo2C monolayer are systematically investigated by using first principles methods. We found that the considered metal atoms are strongly bound to the Mo2C monolayer. ... -
Model study of a surfactant on the GaAs(100) surface
(Elsevier, 2002-11-01)Based on the facts that: (a) the transverse acoustic vibrational branch frequency is softened at the Brillouin zone boundaries of crystalline GaAs; (b) at the surface, the Ga-As bond is stronger than Ga-Te bond; and (c) ... -
Peculiar piezoelectric properties of soft two-dimensional materials
(American Chemical Society, 2016-06)Group II-VI semiconductor honeycomb monolayers have a noncentrosymmetric crystal structure and therefore are expected to be important for nano piezoelectric device applications. This motivated us to perform first-principles ... -
The response of mechanical and electronic properties of graphane to the elastic strain
(AIP Publishing LLC, 2010)Based on first-principles calculations, we resent a method to reveal the elastic properties of recently synthesized monolayer hydrocarbon, graphane. The in-plane stiffness and Poisson’s ratio values are found to be smaller ... -
Structural and electronic properties of MoS2, WS2, and WS2/MoS2 heterostructures encapsulated with hexagonal boron nitride monolayers

TiO2 assisted sensitivity enhancement in photosensitive nanocrystal skins
(IEEE, 2014-10)Solution-processable semiconductor nanocrystals (NCs) have been widely used to create novel devices for the photovoltaic, light-emission, light-detection and biosensing applications. They are good candidates especially to ... -
Ultrasensitive label-free microcavity biosensors with high selectivity
(IEEE, 2011)High quality factor whispering gallery mode microresonators have been recently shown to exhibit detection sensitivity of single molecule; however, the selectivity of these sensors among different types of analytes remains ... -
Variable energy x-ray photoemission studies of alkylsilane based monolayers on gold
