Highly Crystalline and Oriented Thin Films of Fully Conjugated 3D‐Covalent Organic Frameworks

open access: yesAngewandte Chemie, EarlyView.
This work introduces a fully conjugated, 3D covalent organic framework (COF) based on cyclooctatetrathiophene (COTh); the synthesis employs modulated conditions to achieve thin films with high crystallinity. The COTh‐1P COF shows potential for optoelectronic applications, thanks to its π‐conjugated structure, the preferential film orientation, and ...

The nonlocal boundary problem with perturbations of antiperiodicity conditions for the eliptic equation with constant coefficients

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2018
In this article, we investigate a problem with nonlocal boundary conditions which are perturbations of antiperiodical conditions in bounded $m$-dimensional parallelepiped using Fourier method. We describe properties of a transformation operator $R:L_2(G)

On the Enhanced p‐Type Performance of Back‐Gated WS2 Devices

open access: yesAdvanced Electronic Materials, EarlyView.
A scalable method for directly growing WS2 enables robust and persistent p‐type behavior in back‐gated FETs, independent of metal contacts, thickness, or ambient conditions. Electrical measurements reveal minimal Schottky barrier heights and stable thermionic transport, while first‐principles simulations suggest tungsten vacancies or WO3 species as the

Overcoming Photochemical Limitations in Covalent Organic Frameworks: Low‐Energy Light Driven Selective 1O2 Generation Achieved by Donor–Acceptor Strategy

open access: yesAngewandte Chemie, EarlyView.
We demonstrate for the first time that a novel donor–acceptor strategy in covalent organic frameworks (COFs) has been developed to regulate the localized electronic state structures for efficient and selective 1O2 generation under low‐energy light. The engineered COF selectively produced 1O2 under red light through a coupled charge transfer mechanism ...

Nonlocal problems for hyperbolic equations from the viewpoint of strongly regular boundary conditions

open access: yesElectronic Journal of Differential Equations, 2020
In this article, we consider a nonlocal problem for hyperbolic equation with integral conditions and show their close connection with the notion of strongly regular boundary conditions.

Roughness of the Controllability for Time Varying Systems Under the Influence of Impulses, Delay, and Nonlocal Conditions

open access: yesNonautonomous Dynamical Systems, 2020
In this paper, we prove that the controllability of time varying linear system is preserved if we add impulses, delay and nonlocal conditions on it. In order to do that, we assume some conditions on the non-linear terms and apply the Rothe’s fixed point ...

Achieving Ultra‐Low Contact Resistance via Copper‐Intercalated Bilayer MoS2

open access: yesAdvanced Electronic Materials, EarlyView.
A MoS2‐based transistor, featuring bilayer MoS2 connected to Cu‐intercalated bilayer MoS2 electrodes is designed. At a supply voltage of 0.6 V, the contact resistance is 16.7 Ω µm (zigzag) and 30.0 Ω µm (armchair), approaching or even surpassing the 30 Ω µm quantum limit for single‐layer materials.
