提出了一种单次可编程的金属-分子-金属器件.该器件利用一种经过改良的Rotaxane LB膜作为功能层,可以和应用于场编程门阵列电路中的无机反熔丝器件相比拟,将在有机可编程电路和容错电路等方面有较广泛的应用.所有的加工工艺都是低温工艺,使得该器件可以和其他有机器件集成.电学测试表明该器件有良好的单次编程能力,其击穿电压为2.2V,关态电阻为15kΩ,而开态电阻为54Ω.据分析,这一特性是由非对称的电极结构和金属原子在高电场作用下穿透了分子薄膜所造成的.
A one-time programmable metal-metal-metal device is proposed, which uses an improved Rotaxane LB film as a functional layer and can be compared with inorganic antifuse devices used in field-programmable gate array circuits. Will have a wider range of applications in organic programmable circuits and fault-tolerant circuits, etc. All of the processing techniques are low-temperature processes that allow the device to integrate with other organic devices.Electrical tests show that the device has good single-pass programming capabilities, The breakdown voltage is 2.2V, the off-state resistance is 15kΩ, and the on-state resistance is 54Ω.This characteristic is analyzed by the asymmetric electrode structure and the metal atoms penetrate the molecular thin film under the action of the high electric field.
