Scanning electron microscope image signal-to-noise ratio monitoring for micro-nanomanipulation.

, 2014
International audienceAs an imaging system, scanning electron microscope (SEM) performs an important role in autonomous micro-nanomanipulation applications. When it comes to the sub micrometer range and at high scanning speeds, the images produced by the

Visual Servoing Schemes for Automatic Nanopositioning Under Scanning Electron Microscope.

, 2014
International audienceThis paper presents two visual servoing approaches for nanopositioning in a scanning electron microscope (SEM). The first approach uses the total pixel intensities of an image as visual measurements for designing the control law ...

Electron spin resonance of nitrogen-vacancy centers in optically trapped nanodiamonds

, 2012
Using an optical tweezers apparatus, we demonstrate three-dimensional control of nanodiamonds in solution with simultaneous readout of ground-state electron-spin resonance (ESR) transitions in an ensemble of diamond nitrogen-vacancy (NV) color centers ...

Coupling an epitaxial quantum dot to a fiber-based external-mirror microcavity

, 2009
We report the coupling of individual InAs quantum dots (QDs) to an external-mirror microcavity. The external mirror is bonded to a fiber and positioned above a semiconductor sample consisting of a QD-containing GaAs layer on top of a distributed Bragg ...

Analysis and design of rapid prototyped mechanisms using hybrid flexural pivots [PDF]

, 2015
The ability of fabricating flexure based mechanism is of great importance in modern technology fields such as nanotechnology and precision engineering. For an instance, a great number of nanopositioning systems are made out of flexures. Examples of these

Visualizing the motion of graphene nanodrums

, 2016
Membranes of suspended two-dimensional materials show a large variability in mechanical properties, in part due to static and dynamic wrinkles. As a consequence, experiments typically show a multitude of nanomechanical resonance peaks, which makes an ...

Engineered arrays of NV color centers in diamond based on implantation of CN- molecules through nanoapertures

, 2010
We report a versatile method to engineer arrays of nitrogen-vacancy (NV) color centers in dia- mond at the nanoscale. The defects were produced in parallel by ion implantation through 80 nm diameter apertures patterned using electron beam lithography in ...
