Nanoscale MOSFET Modeling for the Design of Low-power Analog and RF Circuits

This paper presents the simplified charge-based EKV MOSFET model and shows that it can be used for advanced CMOS processes despite its very few parameters. The concept of inversion coefficient is then presented as an essential design parameter that spans t ...

A Computational and Experimental Study of Thieno[3,4-b]thiophene as a Proaromatic pi-Bridge in Dye-Sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Shaik Mohammed Zakeeruddin, Fabrizio Giordano

Four D-pi-A dyes (D=donor, A=accpetor) based on a 3,4-thienothiophene pi-bridge were synthesized for use in dye-sensitized solar cells (DSCs). The proaromatic building block 3,4-thienothiophene is incorporated to stabilize dye excited-state oxidation poten ...

200 km fiber-loop Brillouin distributed fiber sensor using bipolar Golay codes and a three-tone probe

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Zhisheng Yang

Aiming at taking full advantage of bipolar codes, a method using a three-tone probe is proposed to alleviate the probe power limitation imposed by pump depletion in Golay-coded Brillouin distributed fiber sensors. Experimental results validate the techniqu ...

Quantum state specific reactant preparation in a molecular beam by rapid adiabatic passage

Rainer Beck, Helen Jane Chadwick, Phil Morten Hundt, Bruce Yoder

Highly efficient preparation of molecules in a specific rovibrationally excited state for gas/surface reactivity measurements is achieved in a molecular beam using tunable infrared (IR) radiation from a single mode continuous wave optical parametric oscill ...

Fluorogenic probes for live-cell imaging of the cytoskeleton

Kai Johnsson, Luc Reymond, Grazvydas Lukinavicius, Mathias Fournier, Anastasiya Masharina

We introduce far-red, fluorogenic probes that combine minimal cytotoxicity with excellent brightness and photostability for fluorescence imaging of actin and tubulin in living cells. Applied in stimulated emission depletion (STED) microscopy, they reveal t ...

Practical issues related to the design of UWB directional couplers in strip line technology

Juan Ramon Mosig, Baptiste Fernand Hornecker

Recently, the study of slot-coupled directional couplers has led to compact and elegant topologies for UWB applications. The most common design consists in two elliptically shaped lines coupled through an elliptically shaped slot in a common ground plane. ...

Phosphorescence of iridium(III) complexes with 2-(2-pyridyl)-1,3,4-oxadiazoles

Michael Graetzel, Mohammad Khaja Nazeeruddin, Rosario Scopelliti

Cationic bis-cyclometalated iridium(III) complexes (C boolean AND N)(2)Ir(N boolean AND N) with 2-(2'-pyridyl)-5-R-1,3,4-oxadiazoles (N boolean AND N; R = 1-adamantyl, mesityl, N-diphenylamino) have a redox gap of 2.58-2.68 V and exhibit orange-red ...

How to blue-shift phosphorescence color of iridium(III) complexes

Michael Graetzel, Mohammad Khaja Nazeeruddin, Rosario Scopelliti

We achieve a 20-58 nm (610-1890 cm (1)) blue-shift of the phosphorescence maximum of iridium(III) complexes (CN)(2)Ir(NN) of 1,10-phenanthrolines (NN) by modifying the cyclometalating 2-phenylpyridine ligand (CN = ppy) with an electron-w ...

Fluorescence correlation spectroscopy with a total internal reflection fluorescence STED microscope (TIRF-STED-FCS)

Theo Lasser, Marcel Leutenegger

We characterize a novel fluorescence microscope which combines the high spatial discrimination of a total internal reflection epi-fluorescence (epi-TIRF) microscope with that of stimulated emission depletion (STED) nanoscopy. This combination of high axial ...
