Vortex rectenna powered by environmental fluctuations [PDF]

open access: yesNature Communications, 2018
AbstractA rectenna, standing for a rectifying antenna, is an apparatus which generates d.c. electricity from electric fluctuations. It is expected to realize wireless power transmission as well as energy harvesting from environmental radio waves. To realize such rectification, devices that are made up of internal atomic asymmetry such as an asymmetric ...

MIM‐Diode‐Like Rectification in Lateral 1T/1H/1T‐MoS2 Homojunctions via Interfacial Dipole Engineering

open access: yesAdvanced Electronic Materials, Volume 12, Issue 3, 4 February 2026.
The metallic 1T and semiconducting 1H phases of MoS2 enable phase‐engineered 1T/1H/1T homojunctions that exhibit MIM‐diode‐like rectification without dissimilar electrodes. Asymmetric 1T/1H interfaces induce interface dipoles and a built‐in potential drop across the 1H barrier, creating a trapezoidal tunnel barrier at zero bias and yielding diode‐like ...
