Themed collection In Honor of Professor Thom Palstra

A special collection in honor of Professor Thom Palstra on the occasion of his retirement.

Transistors based on delicate electronic materials are frequently tested under extreme biasing conditions. Using in situ IR imaging of biased devices, we show that local temperature of channels in such studies can very quickly rise well above 150 °C.

This review highlights current advances in magnetic-property tuning of layered materials by means of intercalation, and provides challenges and opportunities for materials chemists to advance the field.

Purification and functionalization of SWCNTs with HCl reduces impurities, and annealing Si/P-SWCNT/ZnO solar cells improves performance, achieving 18.6% efficiency with excellent photoresponse.

First-order character of the ferroelectric phase transition in BaTiO₃ (BT) is maintained by Na_0.5Bi_0.5TiO₃ (NBT) substitution, which in turn causes large electrocaloric response.

The one-step laser powder bed fusion method, without the need for heat treatment, successfully produces a microstructure containing austenite phase in NiMnSn samples. An impressive elastocaloric temperature change of 6.7 K was obtained.

Germanene maintains its topological edge states at room temperature despite thermal smearing of the bulk band gap. These states can be controlled by a perpendicular electric field, highlighting its potential for low-energy electronic applications.

This study investigates the temperature dependence of conductivity in molecular junctions under various biasing regimes, providing insights into charge transport mechanisms and their impact on device functionality.

Mixing a Dion–Jacobson spacer and a Ruddlesden–Popper spacer regulates quasi-2D perovskite thin films for a normal-gradient phase distribution, while FACl additive doping regulates the films to give a reversed-gradient phase distribution.

Resonant elastic X-ray scattering at the V K edge reveals systematic variations of the resonant forbidden (002) reflection in thin films of spinel LiV₂O₄ deposited on MgAl₂O₄, SrTiO₃, and MgO.

Our experimental and theoretical studies have inferred that tin bromide is more susceptible to form higher order 2D Ruddlesden-Popper or 3D perovskite nanostructures than lead bromide.

The persistence of ferroelectricity down to nanometer scales in hafnia-based materials makes these compounds promising candidates for future electronic applications.

Colloidal perovskite nanoplatelets (NPLs) have shown promise in tackling blue light-emitting diode challenges based on their tunable band gap and high photoluminescence efficiencies.

The temperature dependence of the polarized Raman spectrum of antiferromagnetic CrPS₄ suggests a correlation between the phonon modes and the magnetic phase transition.

Temperature dependent Raman spectroscopy combined with density functional theory calculations reveal anisotropic electron–phonon coupling in the low-symmetry transition metal dichalcogenide PdSe₂.
