Multiscale 2D/3D microshaping of property-contrast polymer-derived SiCN

Polymer-derived ceramics are a unique class of materials known for their outstanding properties and versatile applicability. The liquid nature of the precursors allows easy addition of fillers in order to alter the resulting ceramics’ properties. We use a ...

Single-Walled Black Phosphorus Nanotube as a NO(2 )Gas Sensor

Xiao Zhou, Cheng Chen, Pengfei Ou

An ab initio density functional theory study on the candidacy of single-walled black phosphorus nanotubes (BPNTs) towards sensing several common toxic gas molecules (NH3, CO, NO, NO2, and SO2) was conducted. Various adsorption characteristics, including th ...

Many-body Green?s function approach to lattice thermal transport

Nicola Marzari, Michele Simoncelli

Recent progress in understanding thermal transport in complex crystals has highlighted the prominent role of heat conduction mediated by interband tunneling processes, which emerge between overlapping phonon bands (i.e., with energy differences smaller tha ...

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 ...

Proximity-Induced Novel Ferromagnetism Accompanied with Resolute Metallicity in NdNiO3 Heterostructure

Joël Mesot, Zoran Ristic, Marco Caputo, Zheng Wang, Anna Zakharova

Employing X-ray magnetic circular dichroism (XMCD), angle-resolved photoemission spectroscopy (ARPES), and momentum-resolved density fluctuation (MRDF) theory, the magnetic and electronic properties of ultrathin NdNiO3 (NNO) film in proximity to ferromagne ...

Magnetic electron collimation in three-dimensional semi-metals

Philip Johannes Walter Moll, Matthias Carsten Putzke, Chunyu Guo, Jonas De Jesus Diaz Gomez

While electrons moving perpendicular to a magnetic field are confined to cyclotron orbits, they can move freely parallel to the field. This simple fact leads to complex current flow in clean, low carrier density semi-metals, such as long-ranged current jet ...

Temperature dependence of reconfigurable bandstop filters using vanadium dioxide switches

Mihai Adrian Ionescu, Matteo Cavalieri, Andrei Müller

In this Letter, we report and investigate the temperature dependency of various radio frequency (RF) parameters for a fabricated reconfigurable bandstop filter with vanadium dioxide (VO2) switches measured up to 55 GHz. Here, the insulator-to-metal (ITM) a ...

Length scales of interfacial coupling between metal and insulator phases in oxides

Duncan Thomas Lindsay Alexander, Bernat Mundet, Jean-Marc Triscone

The characteristic length scale and mechanism of the metal-insulator transition in nickelate superlattices is addressed, with implications for the design of oxide electronics. Controlling phase transitions in transition metal oxides remains a central featu ...

Electronic structure of pristine and Ni-substituted LaFeO3 from near edge x-ray absorption fine structure experiments and first-principles simulations

Nicola Marzari, Iurii Timrov, Artur Braun, Matteo Cococcioni, Xinyu Zhang, Daniele Passerone, Piyush Agrawal

We present a joint theoretical and experimental study of the oxygen K-edge spectra for LaFeO3 and homovalent Ni-substituted LaFeO3 (LaFe0.75Ni0.25O3), using first-principles simulations based on density-functional theory with extended Hubbard functionals a ...
