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

Advanced Electronic Materials, EarlyView.
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/

RRAM Variability Harvesting for CIM‐Integrated TRNG

Advanced Electronic Materials, EarlyView.
This work demonstrates a compute‐in‐memory‐compatible true random number generator that harvests intrinsic cycle‐to‐cycle variability from a 1T1R RRAM array. Parallel entropy extraction enables high‐throughput bit generation without dedicated circuits. This approach achieves NIST‐compliant randomness and low per‐bit energy, offering a scalable hardware

High‐Speed Flexible Schottky Diodes Based on Carbon Nanotubes

Advanced Electronic Materials, EarlyView.
We demonstrate a flexible Schottky diode based on carbon nanotube network thin film, and the devices are fabricated via a low‐temperature process on a PI substrate, which exhibits excellent radio‐frequency characteristics, with a high responsivity 6 A/W at zero bias, a high intrinsic cut‐off frequency reaching 153 GHz, and an extrinsic cut‐off ...
