The Centre for Research on Adaptive Nanostructures and Nanodevices (CRANN) is Ireland’s flagship nanoscience research institute.
CRANN delivers world-leading nanoscience and materials science research, in particular specialising in nanostructure fabrication and characterisation.
Its researchers are involved in a range of cutting-edge projects including nanoelectronic device fabrication, photonics, biosensors for measurement of membrane protein-ligand interactions, spintronics, 2D nanosheet isolation and nanomechanics.
Network Role: The Advanced Microscopy Laboratory (AML) in CRANN (the Centre for Research on Adaptive Nanostructures and Nanodevices) plays a key role in PicoFIB pushing the limits of Ion Beam patterning for nanostructure fabrication down to the atomic level. CRANN has Irelands only He/Ne/Ga triple-beam FIB facility, with expertise in both ion and e-beam patterning for functional device development. PicoFIB accesses important functional device characterisation expertise including in-situ 4-probe electrical characterisation, photoluminescence, cathodoluminescence. The AML also coordinates He-processing of functional 2D materials and graphene.

"My current research is focused on the development and applications of scanning helium ion microscopy (HIM). To understand the unique contrast mechanisms provided by He ions, I am interested in the physics of ion-matter interaction and details of signal generation and detection."
"For the helium ion microscope, is it possible to achieve atomic resolution, high-sensitive analysis and clean milling with Angstrom precision?"
