Enhanced Photoresponse in Intermingled WS2 and MoS2 Nanodiscs on Graphene Heterostructure Nanohybrids

Advanced Materials Interfaces, EarlyView.
Intermingled WS2 and MoS2 nanodiscs on graphene made using alternative coatings of MoS2 and WS2 to achieve optimal morphology and high concentration of the nanodiscs to enable localized surface plasmonic resonance for enhanced light absorption and photodetection. Comparing the three samples, the highest photoresponsivity is obtained on WMW‐NDs/graphene

The Exoplanet Edge: Planets Do Not Induce Observable Transit Timing Variations with a Dominant Transit Timing Variation Period Faster than Half Their Orbital Period

The Astrophysical Journal Letters
Transit timing variations (TTVs) are observed for exoplanets at a range of amplitudes and periods, yielding an ostensibly degenerate forest of possible explanations.

The Absolute Parameters of The Detached Eclipsing Binary V482 Per

, 2015
We present the results of the spectroscopic, photometric and orbital period variation analyses of the detached eclipsing binary \astrobj{V482~Per}. We derived the absolute parameters of the system (M$_{1}$ = 1.51 M$_{\odot}$, M$_{2}$ = 1.29 M$_{\odot ...

Contactless Tracking of Decomposition in Self‐Reporting Ceramic Cr‐Al‐B Coatings

Advanced Materials Interfaces, EarlyView.
Proof of concept for contactless tracking of decomposition in self‐reporting ceramic Cr‐Al‐B coatings in extreme environments by contactless resistivity measurements is demonstrated. To verify the results, high resolution in situ and ex situ methods are employed.

Period changes in six contact binaries: WZ And, V803 Aql, DF Hya, PY Lyr, FZ Ori, and AH Tau

, 2008
Six contact binaries lacking a period analysis have been chosen to search for the presence of a third body. The O-C diagrams of these binaries were analyzed with the least-squares method by using all available times of minima.

Surface Properties of p‐GaN and Formation of Nickel Metal Contacts

Advanced Materials Interfaces, EarlyView.
The amount of C, O, and Mg–O bonds on the surface of p‐GaN can be reduced while still maintaining the surface morphology by potassium hydroxide (KOH) wet chemical treatment. Heating this surface with Ni on top in ultra‐high vacuum (UHV) results in a crystalline Ga‐Ni alloy and diffusion of Ga, which creates vacancies close to valence band leading to ...

Integrated Ovonic Threshold Switching Selector and Resistive Switching Memory 1S1R in Electrodeposited ZnTe Thin Films

Advanced Materials Technologies, EarlyView.
This study showcases the first‐ever demonstration of ovonic threshold switching (OTS) and resistive switching (RS) in ZnTe thin films fabricated via a fast, cost‐effective electrodeposition method. By controlling the deposition potential, ZnTe film is tuned to demonstrate OTS or RS behaviors, enabling the implementation of one‐selector‐one‐resistor ...

How to Manufacture Photonic Metamaterials

Advanced Materials Technologies, EarlyView.
Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.
