Moiré superlattices at the topological insulator Bi2Te3
We report on the observation of complex superlattices at the surface of the topological insulator Bi2Te3. Scanning tunneling microscopy reveals the existence of two different periodic structures in addition to the Bi2Te3 atomic lattice, which is found to strongly affect the local electronic structure. These three different periodicities are interpreted to result from a single small in-plane rot...
متن کاملMajorana modes in a topological insulator/s-wave superconductor heterostructure
In a recent experiment, signatures of Majorana fermion (MF) were found in the vortex core threading a heterostructure composed of n layers of topological insulator (TI) deposited on a bulk s-wave superconductor. Here we provide strong theoretical support to the experiment. First, we demonstrate that MF modes appear on both top and bottom layers of TI, and are well separated for n ~ 6. The top M...
متن کاملMoiré topography.
Contour moiré pictures with good contrast of a full size living body are now available. Construction problems, performance, and accuracy of large instruments are experimentally studied. Techniques to minimize the drawbacks of the moiré contouring are developed. The system has been proved to be ready for practical application to full size living bodies.
متن کاملIntensity-modulated moiré topography.
Moiré topography has the advantage of requiring only a single image to obtain a three-dimensional measurement, but it cannot discern the fringe order. Because there is an ambiguity problem when calculating the depth range by use of fringe intensity or phase unwrapping, it is impossible to obtain an absolute phase and an absolute depth range. It is therefore difficult to discern the relation bet...
متن کاملHeterodyne moiré surface profilometry.
In this study, a novel moiré fringe analysis technique is proposed for measuring the surface profile of an object. After applying a relative displacement between two gratings at a constant velocity, every pixel of CMOS camera can capture a heterodyne moiré signal. The precise phase distribution of the moiré fringes can be extracted using a one-dimensional fast Fourier transform (FFT) analysis o...
