Large-scale molecular dynamics simulation of surface nanostructuring with a laser-assisted scanning tunnelling microscope

In this work, large-scale molecular dynamics simulations are conducted to explore the thermal and mechanical phenomena in surface nanostructuring with a laser-assisted scanning tunnelling microscope. Employing a super parallel computer, more than 200 million atoms are modelled to provide substantial details about how the localized thermal and mechanical perturbations result in surface nanostruc...

A custom confocal and two-photon digital laser scanning microscope.

We describe a custom one-photon (confocal) and two-photon all-digital (photon counting) laser scanning microscope. The confocal component uses two avalanche photodiodes (APDs) as the fluorescence detector to achieve high sensitivity and to overcome the limited photon counting rate of a single APD ( approximately 5 MHz). The confocal component is approximately nine times more efficient than our ...

Studying of various nanolithography methods by using Scanning Probe Microscope

The Scanning Probe Microscopes (SPMs) based lithographic techniques have been demonstrated as an extremely capable patterning tool. Manipulating surfaces, creating atomic assembly, fabricating chemical patterns, imaging topography and characterizing various mechanical properties of materials in nanometer regime are enabled by this technique. In this paper, a qualified overview of diverse lithog...

A New Multichannel Spectral Imaging Laser Scanning Confocal Microscope

We have developed a new multichannel spectral imaging laser scanning confocal microscope for effective detection of multiple fluorescent labeling in the research of biological tissues. In this paper, the design and key technologies of the system are introduced. Representative results on confocal imaging, 3-dimensional sectioning imaging, and spectral imaging are demonstrated. The results indica...
