Direct growth of single-layer terminated vertical graphene array on germanium by plasma enhanced chemical vapor deposition
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-26)Vertically aligned graphene nanosheet arrays (VAGNAs) exhibit large surface area, excellent electron transport properties, outstanding mechanical strength, high chemical stability, and enhanced electrochemical activity, which makes them highly promising for application in supercapacitors, batteries, fuel cell catalysts, etc. It is shown that VAGNAs terminated with a high-quality single-layer graphene ... -
Enhanced photoelectrochemical performance of atomic layer deposited Hf-doped ZnO
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-08)Generation of hydrogen using photoelectrochemical (PEC) water splitting has attracted researchers for the last two decades. Several materials have been utilized as a photoanode in a water splitting cell, including ZnO due to its abundance, low production cost and suitable electronic structure. Most research attempts focused on doping ZnO to tailor its properties for a specific application. In this ... -
Revealing the Quasi-Periodic Crystallographic Structure of Self-Assembled SnTiS3 Misfit Compound
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-28)Chemical vapor transport synthesis of SnTiS3 yields a self-assembled heterostructure of two distinct constituent materials, the semiconductor SnS and the semimetal TiS2. The misfit layer compound, although thermodynamically stable, is structurally complex, and precise understanding of the structure is necessary for designing nanoengineered heterojunction compound devices or for theoretical studies. ... -
Superposition of semiconductor and semi-metal properties of self-assembled 2D SnTiS3 heterostructures
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-15)Two-dimensional metal dichalcogenide/monochalcogenide thin flakes have attracted much attention owing to their remarkable electronic and electrochemical properties; however, chemical instability limits their applications. Chemical vapor transport (CVT)- synthesized SnTiS<sub>3</sub> thin flakes exhibit misfit heterojunction structure and are highly stable in ambient conditions, offering a ... -
Thickness-Dependent Resonant Raman and E' Photoluminescence Spectra of Indium Selenide and Indium Selenide/Graphene Heterostructures
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-28)Atomically thin, two-dimensional (2D) indium selenide (InSe) has attracted considerable attention because of the dependence of its bandgap on sample thickness, making it suitable for small-scale optoelectronic device applications. In this work, by the use of Raman spectroscopy with three different laser wavelengths, including 488, 532, and 633 nm, representing resonant, near-resonant, and conventional ...
