Ferroelectric glass-ceramics [PDF]

open access: yes
Ferroelectric glass-ceramics have been investigated from the Bi203-Ge02, BiOl.s-Ge02-B0I.5, Bi0I.5-Ge02-Te02, 5PbO-3Ge02, PbO-Ge02-NbzOs, and PbsGe30u-PbNbz06-Si02+15%Ah03 systems. DTA, XRD and SEM analysis were used to obtain crystallographic and microstructural information.

Thermoreflectance Detection of Point Defects Resulting from Focused Ion Beam Milling

open access: yesAdvanced Engineering Materials, Volume 28, Issue 11, 3 June 2026.
Focused ion beam (FIB) milling is a common tool for nanoscale material processing, however irradiation damage, redeposition, and contamination can occur. We use several characterization tools to show FIB‐induced effects beyond 1 mm from the milled area.

A New Threshold Switching Device With Tunable Negative Differential Resistance Based on ErMnO3 Polymorphs

open access: yesAdvanced Functional Materials, Volume 36, Issue 44, 1 June 2026.
Polymorph engineering in ErMnO3 enables low‐voltage, forming‐free threshold switching with tunable negative differential resistance. Conducting orthorhombic regions embedded in an insulating hexagonal matrix provide controlled Joule‐heating‐enhanced Poole–Frenkel transport. The hexagonal phase prevents excessive heating and breakdown.
