Rectenna design for K band application [PDF]
2014 44th European Microwave Conference, 2014 An ultra-compact (2.5 cm 2) rectenna design based on an innovative topology using a coplanar stripline connected to a crossed dipoles antenna array is reported here. Experimental results in the K-band show that a DC power up to 0.9 mW can be harvested on a 0.3 kΩ load by using the proposed compact rectenna for incident power density of 1413 µW/cm 2 ...

Advanced 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 ...

Advanced Electronic Materials, Volume 12, Issue 4, 18 February 2026.This study introduces a new method for fabricating MIIM diodes using ultra‐precise dispensing printing techniques combined with ALD. Thus, it provides a practical alternative to traditional lithography. The fabricated diode, with a contact area of 5.4 µm × 4.0 µm exhibits a tunneling current in the microampere range, a zero‐bias responsivity of −1.31 A/

160 GHz Schottky Diodes from Solution‐Processed IGZO
Small, Volume 22, Issue 10, 17 February 2026.A simple, scalable method for contact engineering of planar asymmetric nanogap electrodes enables the development of Schottky diodes with a cut‐off frequency of 160 GHz. Applying these diodes to radio‐frequency rectifying circuits yields output voltages in the range of 0.3–0.74 volts.
