Fundamental and recent progress of Atomic Force Microscopy (Chinese/中文)

March 19, 2020 11:00-12:00 (CST) Beijing

*Note: This webinar will be presented in Mandarin /中文

Nanoscience and technology is one of the most potential research fields in the current fundamental sciences and high-tech. The nanoscale characterization and measurement techniques, including Electron Microscopy, Scanning Probe Microscopy (SPM) and Super-Resolution Optical Microscopy, play key roles in the developing progress of Nano-S&T. Until now, a series of SPM techniques, especially Scanning Tunneling Microscopy (STM) and Atomic Force Microscopy (AFM), have become the core research tools for the materials’ structure, properties and functions at the micro- and nano-scale. As the most extensive SPM techniques, AFM can also be in corporate with the other spectroscopy techniques to realize their nanoscale characterization capabilities in real-space.
In this three-time talk, (1) the fundamental of SPM will be brief introduced firstly, then the basic theory, instrumentation and methods of AFM will be discussed detailed; (2) the three common AFM working modes and their specific applications; (3) the functional AFM modes and their basic principles and applications in the research of materials’ properties at the micro- and nanoscale. A brief comment on the further development of AFM probe techniques and their expanding application areas are also supplied.

Graphene-coated nanoprobe — New approach to obtain conductive probes with enhanced reliability and lifetime

Thursday, December 19, 2019

15:00-16:00 (CST) Beijing
*Note: This webinar will be presented in Mandarin /中文

Graphene-coated nanoprobe

Nanoprobes are highly required in many fields of science, including physics, mechanics, microelectronics, nanotechnology, medicine and biology, as they allow fabrication and characterization with high spatial resolution. But, unfortunately, most nanoprobes available in the market lose their initial good performance extremely fast after some scans or spectroscopic measurements, especially during electrical or mechanical experiments. This webinar will introduce the use of high-quality solution-processed (and spray-coating) graphene sheets to enhance the performance of ultra-sharp nanoprobes. The results prove that graphene-coated nanoprobes not only ensure obtaining high-resolution images, but also enhance the reliability and lifetime. The simplicity and low cost of this method, which can be used to coat any kind of sharp tip, make it suitable for the industry, allowing production on demand. Moreover, the selection of conductive probes referring to the experimental requirements will also be introduced.

Detectores Piroeléctricos DLaTGS

Para muchos, la industria electrónica ha sido la piedra angular para lograr la prosperidad de la era moderna. La electrónica ha transformado por completo casi todas las facetas de la vida cotidiana, alimentando una demanda social y económica casi insaciable para mejorar continuamente nuestros dispositivos. Una de las principales formas de hacerlo es que las compañías de dispositivos produzcan dispositivos portátiles más rápidos, más pequeños, más baratos y más eficientes. Sin embargo, las dimensiones críticas de estos productos deben diseñarse por orden de nanómetros. La caracterización de las propiedades eléctricas a un tamaño nanométrico, como las interacciones de fuerza electrostática, cargas superficiales, conductividad y capacitancia electrostática determina directamente la calidad y el rendimiento del producto en cada dispositivo. Sin embargo, tal caracterización es algo que no se puede hacer fácilmente a escala industrial con las herramientas existentes.
La alta resolución a nanoescala y la alta sensibilidad de AFM pueden cumplir los requisitos altamente desafiantes de la caracterización de propiedades eléctricas a nanoescala. Park AFM proporciona herramientas de detección de propiedades eléctricas de calidad industrial con alta productividad a nuestros clientes tanto en investigación como en la industria..
