Rubbery Schottky Diodes Based on Soft, Stretchy Electronic Materials (Penn State)


A new technical paper titled “Fully rubbery Schottky diode and integrated devices” was published by researchers at Penn State University. The Office of Naval Research and the National Science Foundation funded this research.

“Here, we report a fully rubbery Schottky diode constructed all based on stretchable electronic materials, including a liquid metal cathode, a rubbery semiconductor, and a stretchable anode. The rubbery Schottky diode exhibited a forward current density of 6.99 × 10−3 A/cm2 at 5 V and a rectification ratio of 8.37 × 104 at ±5 V. Stretchy rectifiers and logic gates based on the rubbery Schottky diodes were developed and could retain their electrical performance even under 30% tensile stretching. With the rubbery diodes, fully rubbery integrated electronics, including an active matrix multiplexed tactile sensor and a triboelectric nanogenerator–based power management system, are further demonstrated,” states the paper.
