Effect of the Si/SiO2 Interface on Diffusion in SiO2

Hyomen Kagaku, 2005
Using 30Si-implanted 28SiO2 and natSiO2/28SiO2 structures, Si self-diffusion in SiO2 was studied as a function of temperature and SiO2 thickness (200−650 nm). Si self-diffusivity increased by about one order of magnitude with decreasing SiO2 thickness from 650 to 200 nm with a SiN layer, i.e., the shorter the distance between the 30Si diffusers and the

Solution‐Processed Two‐Dimensional Indium Oxide on Sodium‐Embedded Alumina for Reconfigurable Optoelectronic Synaptic Transistors

Advanced Functional Materials, EarlyView.
Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance

Electrode and Microstructure Dependence of Oxygen Diffusion in Ferroelectric Hafnium Zirconium Oxide Thin Films

Advanced Functional Materials, EarlyView.
Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

Cathodoluminescence Properties of SiO2: Ce3+,Tb3+, SiO2:Ce3+, Pr3+ and SiO2: PbS

, 2012
Silicon dioxide (SiO2), also known as silica, is an oxide of silicon (Si) that is found in nature in two different forms, namely amorphous and crystalline. Traditionally, amorphous SiO2 is used in many applications such as semiconductor circuits, microelectronics and optical fibers for telecommunication.

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies

Advanced Functional Materials, EarlyView.
The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.
