Monolayers of transition metal dichalcogenides, such as molybdenum disulfide, are a potential platform for two-dimensional carrier transport. However, although single-crystalline monolayer channels have been grown at the wafer scale using unidirectional coalescence epitaxy, achieving coherent two-dimensional transport at similar scales remains challenging. This is mainly due to the presence of residual crystalline defects, such as one-dimensional extended and point defects, which emerge when multiple grains coalesce. Here we report an epitaxial growth of single-crystal molybdenum disulfide monolayers at wafer scales in which these defects are minimized by coalescence kinetics control on vicinal sapphire substrates. The resulting channels exhibit coherent transport—manifesting as weak localization and the onset of quantum Hall effects at low temperature—as well as a Hall mobility of 1,200 cm2 V−1 s−1. These coherent channels are used to create arrays of field-effect transistors, which exhibit an average mobility of around 100 cm2 V−1 s−1 and a minimum subthreshold swing of around 65 mV dec−1 at room temperature. By controlling the coalescence of multiple unidirectional grains on vicinal sapphire substrates, wafer-scale channels of single-crystalline molybdenum disulfide can be grown, which exhibit coherent quantum transport across large length scales.

Superconducting travelling-wave parametric amplifiers are promising devices for the near-quantum-limited broadband amplification of microwave signals and are essential for high-quantum-efficiency microwave read-out lines. Built-in isolation, as well as gain, could address their primary limitation: a lack of true directionality due to the potential backward travel of electromagnetic radiation to their input port. Here we report a travelling-wave parametric amplifier isolator that is based on Josephson junctions. The approach uses third-order nonlinearity for amplification and second-order nonlinearity for the frequency upconversion of backward-propagating modes to provide reverse isolation. These parametric processes, enhanced by a phase-matching mechanism, exhibit gain of up to 20 dB and reverse isolation of up to 30 dB over a static 3-dB bandwidth greater than 500 MHz and maintain near-quantum-limited added noise. A Josephson-junction-based travelling-wave parametric amplifier isolator can provide gain of up to 20 dB and reverse isolation of up to 30 dB over a static 3-dB bandwidth greater than 500 MHz and maintain a near-quantum-limited added noise.
