February 3rd, 2025

Our paper on single quantum dot transistors has been published in Nanoscale (RSC). It is a result of collaborative work together with the Institute of Science Tokyo and RIKEN. By precisely anchoring a single PbS quantum dot, we demonstrated resonant tunneling transistors exhibiting multiple negative differential resistance (NDRs), an important milestone for solution-processable quantum electronic devices.
