Steady-state absorption spectraThe steady-state absorbance spectra (Fig. 1a) exhibit an absorption onset at ~1.6 eV and a monotonic increase with photon energy. These features agree with reports on the same compound24 and their relatives (MAPbI3)25. Yang et al. employed a detailed model, based on Elliot’s theory26, to...

The MDI-QKD protocolIn the MDI-QKD protocol, the two end nodes (Alice and Bob) are functionally identical: they randomly choose a string of qubit states, each being one of the four BB84 states (\(\left|0\right\rangle\), \(\left|1\right\rangle\) in the Z-basis and \(\left|\pm \right\rangle =(\left|0\right\rangle \pm \left|1\right\rangle )/\sqrt{2}\)...

We first present the scaling trends of HZO capacitors and the main switching characteristics of the thinnest (5 nm) ferroelectric HZO obtained. Thickness scaling and proper choice of electrode materials are both important for operation of single layer FTJ. Semiconductor bottom electrodes such as Ge...

Electric LC resonators to emulate the Harper-Hofstadter-Hatsugai modelThe features of two-dimensional electrons on a square lattice in a magnetic field with NN (ta and tb in x- and y-directions, respectively) and NNN (tc’) hoppings, called the Harper-Hofstadter-Hatsugai (HHH) model25,34, can be implemented as a...
