With co-locataed instruments, researchers can study samples using Raman and SPM techniques providing detailed information about nanoscale properties and composition. TERS promises to push the resolution limits even further and enable the collection of chemical information on the nanometer scale.
Nanocrystal quantum dots are embedded in a sub-wavelength metallic nanoslit array to produce highly directional emission and beaming of photons. This technology has potential application for displays, biochemical sensing and military.
The Zeta-PSS Package offers quick characterization of High-brightness light emitting diodes (HB-LEDs) substrate bump features. Height, width, and pitch are determined in the same scan. .
Microfluidics is an advancing technology that enables controlling minute liquid quantities. The Zeta-200 Automated 3D metrology system is capable of measuring microfluidic devices that have transparent cover plates, transparent substrate and channels.
Data storage design demands extreme requirements on hard disks and other components. The Zeta-20 3D Imaging and Metrology Microscope measures the parameters that ensure high performance of disk drives such as edge chamfer angle, roughness, disk rolloff, sidewall defects, lube pickup, step heights, defects and roughness.
To use electron or ion beams to create nano-patterns the three methods that are typically used include ion beam milling, beam induced chemistry (deposition and etch), and beam induced lithography. This application note provides instructions for writing, preparing, and developing patterns in hydrogen silsesquioxane (HSQ) films using a Helium Ion Microscope.
Nanotechnology has been well supported in the UK within a rather restricted budget, in ways that have encouraged the effective use of funds and with a clear policy to translate the outputs of basic research into future applications.
