Resistive switching memory devices based on PbS quantum dots

Quantum dots have widely used in a lot of micro-nano photoelectric devices. In this work, PbS quantum dots have been synthesized successfully then a RRAM based on those quantum dots and PMMA mixture material was prepared by solution processed method at room temperature. We have demonstrated that the memory device shows typical resistance switching characteristic and high resistance ratio ( >10⁴). To study the quantum dots based RRAM provides an opportunity to develop the next generation high-performance memory devices and open up a new application field of QDs materials in the future.
