Probing Magnetic Excitations and Correlations in Single and Coupled Spin Systems with Scanning Tunneling Spectroscopy

, 2017
Spectroscopic measurements with low-temperature scanning tunneling microscopes have been used very successfully for studying not only individual atomic or molecular spins on surfaces but also complexly designed coupled systems.

Progress Toward Efficient Wide‐Gap Cu(In,Ga)(S,Se)2 Thin‐Film Solar Cells

Progress in Photovoltaics: Research and Applications, EarlyView.
Wide‐gap Cu (In,Ga)(S,Se)2 thin‐film solar cells are studied in view of their performance, limitations, and opportunities for further optimization. Different sources of open circuit voltage limitations were discussed and weighted. Interface recombination appears the main recombination channel, which however can be influenced heavy alkali treatment ...

Interfacial Atomic and Electronic Structures of LSM/YSZ Thin Films as Models for SOC Air Electrodes

ChemElectroChem, Volume 13, Issue 6, 17 March 2026.
Lanthanum–strontium manganite/yttria‐stabilized zirconia thin films serve as model systems for solid oxide cell electrodes, where high‐resolution scanning transmission electron microscopy and X‐ray photoelectron spectroscopy reveal atomistic interfacial features and electronic structure supported by atomistic modeling of these interfaces.

Inelastic electron tunneling spectroscopy of local “spin accumulation” devices [PDF]

Applied Physics Letters, 2014
We investigate the origin of purported “spin accumulation” signals observed in local “three-terminal” (3T) measurements of ferromagnet/insulator/n-Si tunnel junctions using inelastic electron tunneling spectroscopy (IETS). Voltage bias and magnetic field dependences of the IET spectra were found to account for the dominant contribution to 3T ...

Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Composition and Resulting Band Alignment at the TiO2/InP Heterointerface: A Fundamental Study Combining Photoemission Spectroscopy and Theory

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
The chemical composition and band alignment are systematically investigated at the TiO2/InP heterointerface. Thin TiO2 films are deposited by ALD on atomically ordered, P‐terminated p‐InP(100). By combining UPS, XPS, and ab initio molecular dynamics, the atomistic structure and electronic alignment are revealed.

Inelastic Tunneling into Multipolaronic Bound States in Single-Layer MoS_{2}

Physical Review X
Polarons are quasiparticles that arise from the interaction of electrons or holes with lattice vibrations. Though polarons are well studied across multiple disciplines, experimental observations of polarons in two-dimensional crystals are sparse.

Exploiting Two‐Photon Lithography, Deposition, and Processing to Realize Complex 3D Magnetic Nanostructures

Advanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
Two‐photon lithography (TPL) enables 3D magnetic nanostructures with unmatched freedom in geometry and material choice. Advances in voxel control, deposition, and functionalization open pathways to artificial spin ices, racetracks, microrobots, and a number of additional technological applications.

Interfaces in Large Area 2D Materials Integration: From Epitaxial Growth and Clean Transfer to Interface‐Dominated Performance

Advanced Materials Interfaces, Volume 13, Issue 6, 16 March 2026.
This Review proposes an interface‐centric framework for large‐area 2D materials integration, linking wafer‐scale single‐crystal epitaxy, clean transfer and deterministic stacking, and interface‐dominated structure–property–device correlations. We summarize how interfacial symmetry and energetics govern nucleation/coalescence and adhesion‐controlled ...
