Journal ArticleDOI
Electrical and optical properties of TiO2 anatase thin films
TL;DR: In this article, the metastable phase anatase has been shown to have a wider optical absorption gap than rutile thin films, which is consistent with the high mobility, bandlike conduction observed in anatase crystals.
Journal ArticleDOI
Electronic-Structure of Anatase Tio2 Oxide
TL;DR: In this paper, the experimental density of states (DOS) was found to be in agreement with the theoretical DOS reported in the literature for anatase crystals, and shows some characteristics similar to the experimental DOS reported for rutile crystals.
Journal ArticleDOI
Self-assembly of subnanometer-diameter single-wall MoS2 nanotubes.
Maja Remškar,Ales Mrzel,Z. Skraba,Adolf Jesih,Miran Čeh,Jure Demsar,Pierre Stadelmann,Francis Lévy,Dragan Mihailovic +8 more
TL;DR: The synthesis, structure, and self-assembly of single-wall subnanometer-diameter molybdenum disulfide tubes are reported on, using a novel type of catalyzed transport reaction including C60 as a growth promoter.
Journal ArticleDOI
High mobility n‐type charge carriers in large single crystals of anatase (TiO2)
TL;DR: In this article, resistivity, thermopower, and Hall-effect measurements on large single crystals of the anatase form of TiO2 all indicate high mobility n-type carriers that are produced by thermal excitation from a density of ∼1018 cm−3 putatively present shallow donor states.
Journal ArticleDOI
Superconducting nanowire photon-number-resolving detector at telecommunication wavelengths
Alexander Divochiy,Francesco Marsili,David Bitauld,Alessandro Gaggero,Roberto Leoni,Francesco Mattioli,Alexander Korneev,Vitaliy Seleznev,Nataliya Kaurova,Olga Minaeva,Gregory Goltsman,Konstantinos G. Lagoudakis,Moushab Benkhaoul,Francis Lévy,Andrea Fiore,Andrea Fiore +15 more
TL;DR: The drive to develop detectors capable of counting the number of photons in a weak optical pulse is motivated by potential applications in quantum computing as discussed by the authors, where superconducting nanostructures are one exciting approach: offering high sensitivity and operate at repetition rates up to 80 MHz.
