Resistive switching in atomic layer deposited HfO2/ZrO2 nanolayer stacks
The resistive switching properties of HfO2/ZrO2 nanolayers with the total thickness of 16 nm prepared using atomic layer deposition (ALD) were investigated. Current-voltage behavior, pulse time mode measurement, retention and endurance tests were carried out to characterize the memristive (memory-resistive) properties. Resistive… Read More
Solvent‐deficient method lowers grain‐boundary resistivity of doped ceria
Nanoparticles of gadolinium‐doped cerium oxide (GDC) were synthesized using solvent‐deficient method and their sinterability and electrical properties were investigated using the powder and cold sintering process. The GDC powder was uniaxially pressed into cylindrically‐shaped pellets with a mixture of nitric… Read More
Suppressed Grain Growth in Highly Porous Barium Titanate Foams by Two-step Sintering
Porous barium titanate has gained significant attention in recent years for their potential use in applications such as scaffolds for bone tissue engineering, stress sensors, gas sensors, and many others. However, there is very little control over the grain size… Read More
Enhanced Gamma Ray Sensitivity in Bismuth Triiodide Sensors through Volumetric Defect Control
Some of the more attractive semiconducting compounds for ambient temperature radiation detector applications are impacted by low charge collection efficiency due to the presence of point and volumetric defects. This has been particularly true in the case of BiI3, which… Read More
