Here, PARADIM’s In-House Team developed a simple algorithmic method to separate the two components from ARPES spectra collected with doublet emission sources.

Topological Kondo Insulators offer a unique route to topological surface states with great potentials both for devices as well as to probe the fundamental physics of topology. The NHMFL team came to PARADIM to gain access to what is only the second known topological Kondo insulator, YbB12. Working with PARADIM trainee Lucas Pressley and PARADIM REU Julia Trowbridge, laser floating zone was successfully used to produce untwinned single crystals of YbB12, a very high, incongruently melting, boride, marking the first time this material was produced outside of Japan, and the first time with the laser FZ technique.

In 2020 PARADIM’s in-house team—working with collaborators at Penn State—developed (and patented) a new variant of molecular-beam epitaxy (MBE) called “suboxide MBE.” In contrast to conventional MBE where the molecular beams are elemental, in suboxide MBE the molecular beams are pre-oxidized. This method has since been widely applied by PARADIM users in 20 publications utilizing suboxide MBE + over 20 active user projects).

We demonstrate a method to synthesize superconducting layered square-planar nickelate thin films and set limits on the ability to strain these compounds via epitaxy.

Here, members of PARADIM’s In-House Research Team demonstrate a model system created by stacking a pair of monolayer semiconductors, providing a simpler way to study confounding quantum behavior, from heavy fermions to exotic quantum phase transitions.

Versatile synthetic procedure for preparing mechanically tunable materials using a two-step process of dual cross-linked networks.

Using SAXS to investigate the relationship between molecular design and structure in the linear π-conjugated peptides assembled through a fuel-driven mechanism.

A computationally guided design, synthesis, and application of a water-soluble molecule that acts as a photoremovable protecting group, or photocage, for radical-free Diels-Alder photopatterning.

Peptide-mimicking macromolecules with hydrophobic and cationic side chains that can kill bacteria by destabilizing their membranes.

This publication marks the first time that KTaO3 films have been grown by MBE. The approach used overcame the technical challenges of (1) the low vapor pressure of tantalum (normally impossible in a stable MBE effusion cell due to the low vapor pressure of tantalum) and (2) the safety issues of safely handling potassium, which is highly flammable. The resulting films have the highest structural quality of any KTaO3 films ever grown judging from the narrowness of the x-ray diffraction rocking curves and rather featureless microstructure revealed by STEM.
