Two-atom lead superconductor thinnest ever

All two-dimensional, flexible, transparent, and thinnest thin film transistor.

In this article, we report only 10 atomic layer thick, high mobility, transparent thin film transistors (TFTs) with ambipolar device characteristics fabricated on both a conventional silicon platform as well as on a flexible substrate. Monolayer graphene was used as metal electrodes, 3-4 atomic layers of h-BN were used as the gate dielectric, and finally bilayers of WSe2 were used as the semico...

Delayed Lead Perforation: Can We Ever Let the Guard Down?

Lead perforation is a major complication of cardiac rhythm management devices (CRMD), occurring in about 1%. While most lead perforations occur early, numerous instances of delayed lead perforation (occurring >30 days after implantation) have been reported in the last few years. Only about 40 such cases have been published, with the majority occurring <1 year after implantation. Herein, we desc...

Experiment to Detect Frame Dragging in a Lead Superconductor

Recent work by Tajmar and de Matos predicts a greatly enhanced gravitomagnetic field is measurable in the vicinity of a rotating superconductor. They predict that the associated frame dragging is measurable when the density of Cooper pairs is sufficiently large relative to the mass density. Experimental measurements with superconducting lead and niobium samples reported by the same group suppor...

A Neutral Two Flavor Loff Color Superconductor

In this paper we construct analytically a LOFF color superconducting state that is both color and charge neutral using the weak coupling approximation. We demonstrate that this state is free from chromomagnetic instabilities. Its relevance to the realistic quark matter at moderately high baryon density is discussed.
