Thermodynamic Stability and Site‐Specific Distribution of Graphitic and Pyridinic Nitrogen in Graphene Moiré on Ru(0001)

open access: yesAdvanced Materials Interfaces, EarlyView.
Nitrogen doping on Ru(0001) is investigated using ion implantation and annealing, tuning the distribution of graphitic (GN) and pyridinic (PN) nitrogen sites. STM, XPS, and DFT identified the structure and site distribution, and a thermodynamic phase diagram showed that GN is most stable at the Atop region, while PN preferred boundaries between FCC and

Evaluating Opportunities When People are Uncertainty Averse [PDF]

open access: yes
We consider the problem of ranking sets of alternatives. Standard approaches to this problem regard the addition of an alternative to a set containing one element as enhancing choice.

High Fidelity Waveguides Through Vitreous Media Recomposition for Next Generation Photonic Devices

open access: yesAdvanced Optical Materials, EarlyView.
A newly designed aluminosilicate glass enables the fabrication of femtosecond laser‐written optical waveguides with ultra‐low propagation losses of −0.020 dB cm−1 at 1310 nm and −0.037 dB cm−1 at 1550 nm. Raman, Brillouin, and electron microscopy analyses reveal the mechanisms behind refractive index modifications, highlighting the role of glass ...

Driving Micro‐Objects Using Optical Force due to Fluorescence Emission From Molecules

open access: yesAdvanced Optical Materials, EarlyView.
Emission of fluorescence from a micro‐object in a specific direction is expected to generate an optical force driving the object in the opposite direction of the emission, like a rocket. To demonstrate this ‘photon‐driven micro‐rocket’, we prepared dye‐doped polymer micro‐object (PMO) one surface of which was covered with metallic film; the PMO ...

Bribe-proof Rules in the Division Problem [PDF]

open access: yes
The division problem consists of allocating an amount of a perfectly divisible good among a group of n agents with single-peaked preferences. A rule maps preference profiles into n shares of the amount to be allocated.

Enhancing Amplified Spontaneous Emission in Perovskite Thin Films by Thickness Regulation: Insights into Carrier Distribution and Optical Confinement

open access: yesAdvanced Optical Materials, EarlyView.
This study reveals the critical influence of film thickness and excitation wavelength on the ASE threshold in metal halide perovskites. By optimizing these factors, the ASE threshold is significantly reduced, providing key insights into optical confinement and carrier distribution for advancing electrically pumped perovskite lasers.

Monotonicity and Bounds for Cost Shares under the Path Serial Rule [PDF]

open access: yes
We pursue the analysis of the Path Serial Cost Sharing Rule by examining how the cost share of an agent varies with respect to its own demand and the one of other agents.
