Low-dimensional Materials Characterization with Correlative Microscopy: Raman-AFM-SNOM-SEM


The aim of this webinar is to highlight the benefits of correlative microscopy for studies of graphene and related two-dimensional transition metal dichalogenides (TMDs) such as MoS2 and WS2. Raman Imaging is used to characterize the optoelectronic properties of 2D materials. In combination with AFM and SEM the precise geometric dimensions of these materials is determined. Photonic properties can be gained using SNOM. >

Latest advances in plasma techniques used for atomic layer deposition


Atomic layer deposition (ALD) has established itself as the deposition technique of choice for ultra-thin, controlled, conformal, pin-hole free coatings. In an age of nanotechnology advances ALD is an ideal tool for depositing on nanoscale features.

Professor Erwin Kessels covers:
• recent advances in plasma ALD processing through careful control of the ion energies and plasma conditions to tune the properties of the materials being deposited;
• applications of ALD that have benefited from advanced plasma techniques.

The webinar runs for 45 minutes and includes a question and answer session at the end.

Navigated Atomic Force Microscopy with N8 NEOS


Most atomic force microscopes (AFM) are stand-alone configurations. They either have limited viewing options or only work with transparent samples with less than optimal resolution e.g. in combination with inverted optical microscopes. The N8 NEOS is the first high-performance AFM with the look and feel of an upright optical microscope. The truly seamless integration of the two methods combines both, fast sample navigation and optimum resolution.
The webinar highlights the unique features and upgrade options that make the N8 NEOS a versatile and efficient surface inspection tool. Various applications demonstrate the advantages of a navigated AFM even on samples hardly accessible with conventional instruments.
