Near-Field Integration of a Si3N4 Nanobeam and a SiO2 Microcavity for Heisenberg-Limited Displacement Sensing
Tobias Kippenberg, Dalziel Joseph Wilson, Ryan Daniel Schilling, Vivishek Sudhir, Amir Hossein Ghadimi
A single-chip radio-frequency optomechanical system, consisting of a Si3N4 nanobeam in the evanescent near-field of a SiO2 optical microdisk resonator realizes displacement imprecision >30dB below the standard quantum limit at room-temperature. ...
Ieee20163.6 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 ...
2015Air nonlinear dynamics initiated by ultra-intense lambda-cubic terahertz pulses
Christoph Peter Hauri, Mostafa Shalaby
We report on the measurement of the instantaneous Kerr nonlinearity and the retarded alignment of air molecules CO2, N-2, and O-2 triggered by an intense, lambda-cubic terahertz pulse, a diffraction-and transform-limited single-cycle pulse. The strong-fiel ...
Amer Inst Physics2015The effect of bias in gas temperature measurements on the control of a Solid Oxide Fuel Cells system
Daniel Favrat, Jan Van Herle, Leonidas Tsikonis, Joel Albrektsson
In this paper the effect of systematic errors in gas temperature measurements on the thermal control of a Solid Oxide Fuel Cell system is demonstrated. Three control schemes were tested under two different conditions. First, the real gas temperature at the ...
Elsevier Science Bv2014Low-temperature thin-film indium bonding for reliable wafer-level hermetic MEMS packaging
Nico de Rooij, Danick Briand, Yves Pétremand
This paper reports on low-temperature and hermetic thin-film indium bonding for wafer-level encapsulation and packaging of delicate and temperature sensitive devices. This indium-bonding technology enables bonding of surface materials commonly used in MEMS ...
Institute of Physics2013Tetrathiofulvalene and tetracyanoquinodimethane crystals: Conducting surface versus interface
When a tetrathiofulvalene (TTF) crystal is placed onto a 7,7,8,8‐tetracyanoquinodimethane (TCNQ) crystal at room temperature, a highly conducting layer is formed. In this study, we explore to what degree this is due to physical contact or transfer by subli ...
2012Nature of the Charge Carriers and Conduction Mechanism in Anatase TiO2
The anatase phase of TiO2 is a key material in the third generation of photovoltaics and for photo-catalytic devices. The number of promising applications, where one would profit from the electronic degrees of freedom of the material, like in memristors, s ...
EPFL2012Phosphorescent cationic iridium(III) complexes with cyclometalating 1H-indazole and 2H-[1,2,3]-triazole ligands
Michael Graetzel, Mohammad Khaja Nazeeruddin, Rosario Scopelliti
Two new cationic iridium(III) complexes with cyclometalating 1-phenylindazole or 2-phenyl-1,2,3-triazole ligands, (C boolean AND N)(2)Ir(4,4'-di-tert-butyl-2,2'-dipyridyl), exhibit yellow or green phosphorescence with quantum yields and excited stat ...
Elsevier2012Dilute nitride InGaAsN/GaAs V-groove quantum wires emitting at 1.3 μm wavelength at room temperature
Elyahou Kapon, Alok Rudra, Marco Cantoni, Barbora Bártová, Romain Carron, Pascal Gallo, Marco Felici
Site-controlled InGaAsN quantum wires (QWRs) emitting at 1.3 lm at room temperature were grown on V-grooved GaAs substrates by modulated-flux metallorganic vapor phase epitaxy. The nonplanar substrate template is shown to enhance the nitrogen uptake, evide ...
American Institute of Physics2011Trifluoroacetic Acid-Promoted Synthesis of 3-Hydroxy, 3-Amino and Spirooxindoles from α-Keto-N-Anilides
Ketoanilides containing alkyl side chains were readily cyclized to 3-hydroxy-2-oxindoles or spirooxindoles by a single or double intramolecular Friedel-Crafts reaction in the presence of trifluoroacetic acid (TFA) at room temperature or at 45 degrees C. al ...
