“…For example, Figure 5 a,b show an Al meander and a macroscopic mask for it. Such a superconducting meander with high kinetic inductance [ 33 , 34 ] can be used, e.g., as a current biasing element with high impedance [ 35 ].…”

Micromask Lithography for Cheap and Fast 2D Materials Microstructures Fabrication

The fast and precise fabrication of micro-devices based on single flakes of novel 2D materials and stacked heterostructures is vital for exploration of novel functionalities. In this paper, we demonstrate a fast high-resolution contact mask lithography through a simple upgrade of metallographic optical microscope. Suggested kit for the micromask lithography is compact and easily compatible with a glove box, thus being suitable for a wide range of air-unstable materials. The shadow masks could be either ordered commercially or fabricated in a laboratory using a beam lithography. The processes of the mask alignment and the resist exposure take a few minutes and provide a micrometer resolution. With the total price of the kit components around USD 200, our approach would be convenient for laboratories with the limited access to commercial lithographic systems.

“…Compared with the normal state, shift of the resonance frequency below the transition temperature represents the increase in the inductance of the junction which is interpreted as the kinetic inductance. The geometrical parameters of the superconductor nanowire and theoperation temperature make different values of the kinetic inductance in different superconductor materials as investigated for NbN, 32,33,36 Nb, 36 Ti, and NbN 37 …”

“…The physical parameters of the superconductor nanowires are dependent on the geometrical parameters (length and cross section) of the nanowire, operation temperature, and superconducting material. These dependencies have been widely studied before (as a brief review in previous works 22,[32][33][34][35][36][37] ), and having superconductor nanowires with different physical parameters is practically available by now. In this manuscript, the physical parameters of the QPSJ that are considered in designing of the increased fan-in/fan-out gates are critical voltage, sub-gap resistance, normal resistance, and kinetic inductance, which will be described briefly later.…”

Fan‐in and fan‐out of the quantum phase slip junction (QPSJ)‐based two‐input AND and OR gates are increased for the first time. For increasing their fan‐in, critical voltage, normal and sub‐gap resistances, and kinetic inductance of their constituent QPSJs are changed, and only input and buffer QPSJs are added to the gate. The number of elements in the proposed three‐ and four‐input OR and three‐ and four‐input AND gates is 13, 16, 16, and 20, respectively, which are fewer than those in the serial connection method. For increasing the fan‐out to two, only the mentioned parameters of the constituent QPSJs are changed and no extra element is added to the gate circuits. Comparing with the existing method which adds extra Josephson Junctions and QPSJs to the gate output, the number of elements in the proposed method is that of the basic two‐input gates. For the increased fan‐in/fan‐out OR gates, the critical margins of the external parameters are 10% and 15% of the input voltage, and the critical junction margins are 30% and 26% respectively, while for the increased fan‐in/fan‐out AND gates, they are 9% and 12% of the bias voltage and 26% and 23% for the critical junction margins, respectively.

While in XX century the theory of superconductivity has focused on a homogeneous metal with a rigid lattice which can be reduced to a single effective conduction band in the dirty limit. Today in the XXI century, the physics of superconductivity is focusing on complexity of quantum matter where novel quantum functionalities with lattice inhomogeneity at nanoscale (between 1 nm and 100 nm) and at mesoscopic scale (in the range 100-10000 nm), where the electronic structure need to be described by multiple Fermi surfaces and multiple gaps in the superconducting phase in the clean limit. The present issue of Journal of superconductivity and Novel magnetism collects papers presented at the
