krissKorea Research Institute of Standards and Science (KRISS) has expertise in the fabrication of GaAs-based electron pumps and their characterisation in normal measurement condition at 4 K. In this project, the KRISS Center for Quantum Measurement Science will fabricate and characterise single-electron pump devices made from GaAs-based quantum dots. KRISS will use nano fabrication facilities and low-temperature measurement systems in order to investigate the robustness of the pump device for various parameters such as gate voltages, temperatures and modulating frequencies. KRISS will also provide devices to other partner NMIs for precision measurements and comparison between different pump devices if necessary.
