Trace Iridium Engineering on Nickel Hydroxide Nanosheets as High-active Catalyst for Overall Water Splitting

Designing cost-effective electrocatalysts for electrochemical water splitting to generate the hydrogen energy as a future energy source is pivotal. An excellent catalyst should show high catalytic activity for both hydrogen evolution reaction (HER) and oxy ...

Experimental observation of the acoustic Z2 Weyl semimetallic phase in synthetic dimensions

Romain Christophe Rémy Fleury, Farzad Zangeneh Nejad

Scalar waves such as airborne sound lack an intrinsic spin degree of freedom, making the realization of sonic Z2 topological phases based on spin degeneracy challenging. Here, we demonstrate the relevance of synthetic dimensions and higher-dimensional topo ...

Two-dimensional Material Membranes for Gas Separation

Mostapha Dakhchoune

Two-dimensional (2D) materials with atom- or few-atoms-thick layers have emerged as building-blocks in the synthesis of the next-generation membrane-based separations. Generally, 2D material-based membranes display high permeation and high selectivity due ...

Conformal Passivation of Multi-Channel GaN Power Transistors for Reduced Current Collapse

Elison de Nazareth Matioli, Remco Franciscus Peter van Erp, Halil Kerim Yildirim, Luca Nela, Catherine Erine, Kai Cheng

Multi-channel power devices, in which several AlGaN/GaN layers are stacked to achieve multiple two-dimensional electron gases (2DEGs), have recently led to a significant increase in the device conductivity while maintaining high breakdown voltage, resultin ...

Emergent dual topology in the three-dimensional Kane-Mele Pt2HgSe3

Nicola Marzari, Marco Gibertini, Antimo Marrazzo

Recently, the very first large-gap Kane-Mele quantum spin Hall insulator was predicted to be monolayer jacutingaite (Pt2HgSe3), a naturally occurring exfoliable mineral discovered in Brazil in 2008. The stacking of quantum spin Hall monolayers into a van-d ...

Deep-UV-Enhanced Approach for Low-Temperature Solution Processing of IZO Transistors with High-k AlOx/YAlOx Dielectric

Danick Briand, Jaemin Kim, Alessio Mancinelli

Solution processing is an attractive alternative to standard vacuum fabrication techniques for the large-area manufacturing of metal oxide (MOx)-based electron devices. Here, we report on thin-film transistors (TFTs) based on a solution-processed indium zi ...

Electric-field control of single-molecule tautomerization

Klaus Kern, Christian Alexander Stephan Dette, Shai Mangel, Katharina Polyudov, Tobias Wollandt

The electric field is an important parameter to vary in a single-molecule experiment, because it can directly affect the charge distribution around the molecule. Yet, performing such an experiment with a well-defined electric field for a model chemical rea ...

WSe2/SnSe2 vdW heterojunction Tunnel FET with subthermionic characteristic and MOSFET co-integrated on same WSe2 flake

Mihai Adrian Ionescu, Matteo Cavalieri, Nicolò Oliva, Luca Capua

Two-dimensional/two-dimensional (2D/2D) heterojunctions form one of the most versatile technological solutions for building tunneling field effect transistors because of the sharp and potentially clean interfaces resulting from van der Waals assembly. Seve ...

Quantum Transport in 40-nm MOSFETs a Deep-Cryogenic Temperatures

Edoardo Charbon, Andrea Ruffino, Yatao Peng

In this letter, we characterize the electrical properties of commercial bulk 40-nm MOSFETs at room and deep cryogenic temperatures, with a focus on quantum information processing (QIP) applications. At 50 mK, the devices operate as classical FETs or quantu ...

Insight into the electronic structure of semiconducting epsilon-GaSe and epsilon-InSe

Marco Grioni, Helmuth Berger, Alberto Crepaldi, Daniela Pacilè

Metal monochalcogenides (MX) have recently been rediscovered as two-dimensional materials with electronic properties highly dependent on the number of layers. Although some intriguing properties appear in the few-layer regime, the carrier mobility of MX co ...
