In-line electronic and structural characterization of reactively sputtered Cu-Co-Mn black spinel oxides

Andreas Schueler, Anna Krammer, Maxime Lagier

Cu-Co-Mn spinel oxide thin films are deposited by reactive magnetron sputtering. The x-ray diffraction (XRD) spectrum suggests a nanocrystalline spinel film when sputtered at approximate to 465 degrees C. In-line scanning tunneling microscopy confirms nano ...

The Advantage of Nanowire Configuration in Band Structure Determination

Anna Fontcuberta i Morral, Elias Zsolt Stutz, Simon Robert Escobar Steinvall, Mirjana Dimitrievska

Earth-abundant and environmentally friendly semiconductors offer a promising path toward low-cost mass production of solar cells. A critical aspect in exploring new semiconducting materials and demonstrating their enhanced functionality consists in disenta ...

Extremely large magnetoresistance in the "ordinary" metal ReO3

Oleg Yazyev, Quansheng Wu, Shengnan Zhang, Huancheng Chen

The extremely large magnetoresistance (XMR) observed in many topologically nontrivial and trivial semimetals has attracted much attention in relation to its underlying physical mechanism. In this paper, by combining the band structure and Fermi surface (FS ...

Photoluminescence emission induced by localized states in halide-passivated colloidal two-dimensional WS2 nanoflakes

Raffaella Buonsanti, Anna Loiudice, Jan Vávra, Michele Saba

Engineering physicochemical properties of two-dimensional transition metal dichalcogenide (2D-TMD) materials by surface manipulation is essential to enabling their practical and large-scale application. This is especially challenging for colloidal 2D-TMDs ...

Hidden bulk and surface effects in the spin polarization of the nodal-line semimetal ZrSiTe

Marco Grioni, Arnaud Magrez, Oleg Yazyev, Daniel Gosalbez Martinez, Helmuth Berger, Alberto Crepaldi, Mauro Fanciulli, Gianmarco Gatti

Local inversion symmetry breaking in centrosymmetric materials can lead to large spin polarization of the electronic band structure in separate sectors of the unit cell. Here, the authors reveal such hidden spin polarisation in ZrSiTe using spin and angle ...

Vertex function compliant with the Ward identity for quasiparticle self-consistent calculations beyond GW

Alfredo Pasquarello, Aleksei Tal, Wei Chen

We extend the quasiparticle self-consistent approach beyond the GW approximation by using a range separated vertex function. The developed approach yields band gaps, dielectric constants, and band positions with an accuracy similar to highest-level electro ...

P-GaN Tri-Gate MOS Structure for Normally-Off GaN Power Transistors

Elison de Nazareth Matioli, Pirouz Sohi, Jun Ma, Luca Nela, Catherine Erine, Minghua Zhu

In this letter, we present a new concept for normally-off AlGaN/GaN-on-Si MOS-HEMTs based on the combination of p-GaN, tri-gate and MOS structures to achieve high threshold voltage (V-TH) and low on-resistance (R-ON). The p-GaN is used to engineer the band ...

Electrochemical techniques for photoelectrode characterisation

Isaac Thomas Holmes-Gentle, Franky Esteban Bedoya Lora

Photoelectrodes enable simultaneous light absorption and catalysis of water splitting reactions. Their performance is established using electrochemical characterisation methods. Besides basic characterisation techniques such as voltammetry and chronoampero ...

Correlating chemical and electronic states from quantitative photoemission electron microscopy of transition-metal dichalcogenide heterostructures

Andras Kis, Dumitru Dumcenco, Olivier Renault, Dmitrii Unuchek, Hokwon Kim, Nicolas Chevalier

Vertical heterostructures of MoS2 and WSe2 layers are studied by spectroscopic photoemission electron microscopy as an effective technique for correlating chemical and electronic states at the micrometer scale. Element-specific, surface-sensitive images re ...
