Charge photogeneration in few-layer MoS2

Tetiana Borzda, Christoph Gadermaier, Natasa Vujicic +12

The two-dimensional semiconductor MoS2 in its mono- and few-layer form is expected to have a significant exciton binding energy of several 100 meV, leading to the consensus that ex…

Ferroelectricity and Rashba effect in GeTe

C. Rinaldi, D. Di Sante, A. Giussani +9

GeTe has been proposed as the father compound of a new class of functional materials displaying bulk Rashba effects coupled to ferroelectricity: ferroelectric Rashba semiconductors…

Universal Quasi-Static Limit for Plasmon-Enhanced Optical Chirality

Marco Finazzi, Paolo Biagioni, Michele Celebrano +1

We discuss the possibility of enhancing the chiroptical response from molecules uniformly distributed around nanostructures that sustain localized plasmon resonances. We demonstrat…

Inelastic X-ray scattering from valence electrons near absorption edges of FeTe and TiSe

B. Barbiellini, J. N. Hancock, C. Monney +4

We study resonant inelastic x-ray scattering (RIXS) peaks corresponding to low energy particle-hole excited states of metallic FeTe and semi-metallic TiSe for photon incident e…

One dimensional photonic media characterized by uniform distributions of clusters

Michele Bellingeri, Francesco Scotognella

We realized one dimensional disordered photonic structures by grouping high refractive index layers in clusters, randomly distributed in such structure. We have control on the maxi…

Hysteresis-Free Nanosecond Pulsed Electrical Characterization of Top-Gated Graphene Transistors

Enrique A. Carrion, Andrey Y. Serov, Sharnali Islam +6

We measure top-gated graphene field effect transistors (GFETs) with nanosecond-range pulsed gate and drain voltages. Due to high-k dielectric or graphene imperfections, the drain c…

Tetragonal phase of epitaxial room-temperature antiferromagnet CuMnAs

P. Wadley, V. Novák, R. P. Campion +20

Recent studies have demonstrated the potential of antiferromagnets as the active component in spintronic devices. This is in contrast to their current passive role as pinning layer…

Morphology-driven electrical and optical properties in graded hierarchical transparent conducting Al:ZnO

P. Gondoni, P. Mazzolini, A. M. Pillado Pérez +3

Graded Al-doped ZnO layers, constituted by a mesoporous forest like system evolving into a compact transparent conductor, were synthesized by Pulsed Laser Deposition with different…
