Measurement of the hyperfine structure of the S1/2-D5/2 transition in 43Ca+ [PDF]

, 2006
The hyperfine structure of the S1/2-D5/2 quadrupole transition at 729 nm in 43Ca+ has been investigated by laser spectroscopy using a single trapped 43Ca+ ion. We determine the hyperfine structure constants of the metastable level as A=-3.8931(2) MHz and

Solution Processed Polymer Source‐Gated Transistors for Zero‐Power Photosensing

Advanced Electronic Materials, EarlyView.
This study demonstrates the first solution‐processed bulk heterojunction organic source‐gated transistors (OSGTs) and photo‐OSGTs fabricated using DPP‐DTT: PCBM. Copper‐electrode OSGTs show deep off‐state at zero gate‐source voltage, channel length‐independent on‐state current, and low voltage saturation (γ = 0.22).

Sequential generation of entangled multi-qubit states [PDF]

, 2005
We consider the deterministic generation of entangled multi-qubit states by the sequential coupling of an ancillary system to initially uncorrelated qubits.

In‐Sensor Computing by Soft Threshold Logic Gates Under Different Humidity Conditions

Advanced Electronic Materials, EarlyView.
Soft nanocomposite materials, based on gold cluster‐assembled thin films implanted in polydimethylsiloxane substrate, can perform reliable processing in ambient environmental conditions. Humidity influences the resistive switching and computational capabilities of the nanocomposites, that can be used as multifunctional material combining sensing ...

Light Stability of Laser‐Assisted Glass Encapsulated Perovskite Solar Cells under Different Atmospheres

Advanced Energy Materials, EarlyView.
This study presents a laser‐assisted glass‐frit encapsulation method for perovskite solar cells, comparing air‐, nitrogen‐, and CO2‐filled cavities. Results show that excluding oxygen and moisture significantly improves stability under illumination. The findings reveal the critical role of trapped gases in degradation, providing a pathway to durable ...

Partial Growth of Crack in Laser Scribing of Glass

Journal of the Japan Society for Precision Engineering, 2007
The scribing of glass by a CO2 laser is much more effective compared to the conventional mechanical technology in use because the strength of the cut glass is improved since microcracks and particles along the cut edge are lessened. However, the crack depth of laser scribing is limited because the inner compressive stress region under the cooling area ...

Spontaneous Perovskite Passivator Featuring Dual Functional Groups

Advanced Energy Materials, EarlyView.
A novel strategy to suppress multiple defect sites in perovskite crystals using a spontaneous passivator with dual functional groups is proposed, addressing an intrinsic drawback of conventional spontaneous perovskite passivators. 2‐thiophene‐ethyl‐ammonium‐bis(trifluoromethylsulfonyl)imide (TEA‐TFSI) is newly synthesized and successfully demonstrate ...

Thermal Stress Analysis on Laser Cross Scribe of Glass

Journal of the Japan Society for Precision Engineering, 2008
In CO2 laser scribe processing of glass, an initial crack on the start edge of the glass is indispensable. When carrying out laser cross scribe, there is no initial crack on the edge of the first scribed line. However, the second scribing progresses across the first scribed line. In this research, in order to clarify the phenomena of laser cross scribe,
