Flexible Design of Broadside-Radiating Linearly-Polarized Edge-Fed Metasurface Antennas

open access: yesIEEE Access
In this work, we design and fabricate broadside-radiating edge-fed metasurface antennas with linear polarization employing a spatially-varying isotropic reactance; in order to avoid losses, the antenna is not terminated on a matched load.

Oxygen‐Assisted MOCVD Growth of Monolayer PtSe2 Films With Bandgap Opening for Semiconducting FET Channels

open access: yesAdvanced Science, EarlyView.
Monolayer PtSe2 films are successfully grown via optimized MOCVD, achieving uniform coverage over a 1.5 cm × 1.5 cm area. Oxygen‐assisted growth effectively removes carbon impurities, ensuring high film quality. Array‐level FETs based on monolayer PtSe2 channels demonstrate low off‐current and high ION/IOFF ratios, highlighting the potential of PtSe2 ...

Enhanced Ionic Conductivity at the Solid Electrolyte Interphase of Oxygen‐Doped Li6PS5Cl

open access: yesAdvanced Science, EarlyView.
Machine‐learned molecular dynamics and machine‐learning‐based phase identification reveal the kinetically formed SEI at buried Li | Li6PS5Cl interfaces. The SEI is dominated by Li2S‐based anion‐substituted phases, while oxygen doping enhances SEI ionic conductivity.

Twisted MoS2 Bilayers as Functional Elements in Memtransistors: Hysteresis, Optical Signatures, and Photocurrent Kinetics

open access: yesAdvanced Electronic Materials, EarlyView.
ABSTRACT Layered 2D materials are considered as promising for memristive applications due to their ultimate vertical scalability compared to conventional semiconductor films and pronounced hysteresis properties. Bias‐resolved Raman and Photoluminescence mapping is used to quantify strain from phonon shifts and carrier density from the exciton‐trion ...

An Electronically Switchable Leaky Wave Antenna

open access: yes, 2000
We report an electronically switchable dielectric leaky wave antenna. The main beam angle can be electronically steered using p-i-n diodes. The diodes are used as switches to control the radiation from two sets of gratings with different periods, thereby
