Metal–Insulator–Insulator–Metal (MIIM) Ag/SnO2/Al2O3/Ag Diodes Fabricated by Ultraprecise Dispensing and Atomic Layer Deposition

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.
