How free exciton-exciton annihilation lets bound exciton emission dominate the photoluminescence of 2D-perovskites under high-fluence pulsed excitation at cryogenic temperatures

Michael Graetzel, Jovana Milic, Yang Li, Algirdas Ducinskas

Photoluminescence (PL) spectra of atomically thin 2D lead iodide perovskite films are shown to depend on excited-state density, especially at cryogenic temperatures. At high excited-state densities and low temperatures, free exciton (FE) emission is so sup ...

Strong Coupling of Antiferromagnetic Resonance with Subterahertz Cavity Fields

Jean-Philippe Ansermet, Haiming Yu, Marcin Bialek

Strong coupling of electromagnetic cavity fields with antiferromagnetic spin waves in hematite (alpha-Fe2O3) is achieved above room temperature. A cube of hematite is placed in a metallic tube and the transmission is measured, using a continuous-wave terah ...

Ultralow Dissipation Mechanical Resonators for Quantum Optomechanics

Tobias Kippenberg, Alberto Beccari, Dalziel Joseph Wilson, Nils Johan Engelsen, Sergey Fedorov, Ryan Daniel Schilling, Amir Hossein Ghadimi

We demonstrate dissipation dilution engineering techniques for ultralow dissipation mechanical resonators. The Si3N4 nanobeams show quality factors (Q) as high as 800 million and Q x f exceeding 10(15) Hz-both records at room temperature. (C) 2019 The Auth ...

Geothermometrical characterisation of low-temperature, carbonate-evaporitic geothermal systems is usually hampered by the lack of appropriate mineral equilibria to successfully use most of the classical geothermometers and/or by the thermodynamic uncertain ...

2019

The Tiermas low temperature geothermal system, hosted in the Paleocene-Eocene carbonates of the Jaca-Pamplona basin, has been studied to evaluate the geochemistry and the temperature of the waters in the deep reservoir. These waters are of chloride-sodium ...

Compact and General Strategy for Solving Current and Potential Distribution in Electrochemical Cells Composed of Massive Monopolar and Bipolar Electrodes

Hubert Girault, Alejandro Nicolás Colli

A compact, fast and general algorithm based on Dirichlet boundary conditions for the potential field is derived to enable the calculation of local current distribution, shunt currents and the local potential distribution on massive electrodes in electroche ...

Skyrmion formation in a bulk chiral magnet at zero magnetic field and above room temperature

Henrik Moodysson Rønnow, Jonathan White

We report that in a β-Mn-type chiral magnet Co9Zn9Mn2, skyrmions are realized as a metastable state over a wide temperature range, including room temperature, via field cooling through the thermodynamic equilibrium skyrmion phase that exists below a transi ...

The variation of PbTiO3 bandgap at ferroelectric phase transition

Nava Setter

Optical properties of the PbTiO3 thin films fabricated by chemical solution deposition have been measured with variable angle spectroscopic ellipsometry in the spectral range of 1-6 eV and in the temperature interval from room temperature to 950 K. The opt ...

Bosonic lasing and trapping of a dressed photon fluid in InGaN at room temperature

Munise Nevin Cobet

The generation of a quantum fluid of dressed photons at room temperature is experimentally demonstrated in an InGaN microcavity which is divided into two-and one-dimensional sections, resulting in single- and switchable multilevel coherent light emission. ...

3.6 GHz CMOS Ring Oscillator with Low Tune Voltage Sensitivity and Temperature Compensation

Yusuf Leblebici, Tugba Demirci, Hasene Gülperi Özsema

In this paper we present the design of a temperature compensated low-tune-voltage-sensitive CMOS ring oscillator in 40nm standard CMOS technology. The oscillator has an overall frequency range from 3.1 GHz to 3.6 GHz. The effect of temperature variations o ...
