Carbon Design Innovations, Inc. (CDI) announced the availability of two new atomic force microscope (AFM) probes types with carbon nanotube (CNT) tips. The CCHAR (carbon core high-aspect ratio) and CCHR (carbon core high resolution) CNT probes offer improvements for AFM imaging, substantially improving results, reducing overall cost of operation and opening new avenues for research.
CDI has a patent pending process for the deterministic manufacture of carbon nanotube (CNT) devices. Based on this breakthrough process, the company is able to produce CNT AFM probes that are perfectly straight and precisely aligned, allowing them to be set at desired angles to the surface.
The CNT is at the core of the probe structure and the CNT is securely anchored providing for robust and stable imaging with previously unseen levels of performance. According to CDI, their CNT probes are more stable and have longer imaging lifetimes than other probe types. In addition, the ability to reinforce longer probes and control taper angle provides users with deep-trench scanning ability not currently available. As a result, CDI probes offer customers greater imaging flexibility, performance and reproducibility that will enable them to make significant advances in AFM research. The new CNT AFM probes from CDI are compatible with all major AFM systems.
The CCHAR probe offers high-aspect ratio imaging capability and is designed for materials science, metrology and life science applications. It offers stability and durability in a high-aspect ratio probe designed for difficult to resolve scanning operations such as deep-trench imaging. The nominal CNT total probe length is 1 μ with the exposed CNT length being 500 nm. The CCHAR can be mounted onto any AFM Cantilever.
The CCHR probe family provides high-resolution for material science and life science applications. It offers the durability, stability and high resolution capabilities of a multi-wall CNT tip. The nominal total CNT length is 500 nm, with the exposed CNT tip <200 nm. It can be mounted onto any AFM cantilever.
CDI probes are now available for order and will begin shipping in the third quarter of 2009.
