Patterned Assembly of Quantum Dots onto Surfaces Modified with Click Microcontact Printing

Abstract

The self-assembly of CdSe quantum dots (QDs) onto a patterned silica surface generated from surface microcontact click printing is presented. The mechanically robust self-assembly process produces patterns of QDs which remain steadfast, even as subsequent reactions are performed on the substrate, demonstrating the utility and ease of this self-assembly process.

Magnetic Field Assisted Micro-Contact Printing: A New Concept for a Fully Automated and Calibrated Process

Abstract

This application note presents a new concept - magnetic-field assisted for µCP. The force of the stamp can be tuned by the distance between the stamp and the magnet. The INNOSTAMP40 is fully automated and calibrated for better standardization of the technology.

Microcontact Printing of Ultrahigh Density Gold Nanoparticle Monolayer for Flexible Flash Memories

Abstract

A uniform monolayer of alkanethiol-protected gold nanoparticle arrays with ultrahigh density have been used as microcontact-printable charge-trapping layers for the application in flexible flash memories. The new devices are compared to two reference devices with a floating gate created by thermal evaporation and electrostatic self-assembly, and show a large memory window, long retention times and good endurance properties.
