Nanomaterials and Nanofabrication

Cleaving Applications

In the research environment, one typically does not use the full wafer when fabricating devices. Getting the most out of expensive wafers requires downsizing. Cleaving is a desired sample  method because it is fast, dry and clean. Here we present examples where cleaving is used to downsize nanomaterials and nanofabricated devices. WATCH VIDEOS

Nanofabricated Photonic Devices

Scientists in the Quantum Photonics Group at the Niels Bohr Institute of the University of Copenhagen are developing new technologies for photonic and quantum-information applications. They are using the LatticeAx to alleviate one of their biggest sample preparation challenges: precise cleaves on small samples without damaging delicate fabricated nanostructures.

Cleaving Strontium Titanate (STO)

STO has a cubic crystal structure with a crystal lattice closely matching Perovskite. It is commonly used as a substrate for epitaxially grown films. Although it is cubic it is surprisingly difficult to cleave. We found that using the FlexScribe with a scribing wheel embedded with diamond we could cleave a 5mm2 and 0.5 mm thick STO substrate (100) in to 2.5x2.5 mm samples. The FlexScribe was used to scribe the samples and small samples pliers used for cleaving.
