HAADF STEM and Ab Initio Calculations Investigation of Anatase TiO₂/LaAlO₃ Heterointerface

Applied Sciences, 2022
The understanding of the origin of a two-dimensional electron gas (2DEG) at the surface of anatase TiO2 remains a challenging issue. In particular, in TiO2 ultra-thin films, it is extremely difficult to distinguish intrinsic effects, due to the physics ...

2D Inorganic Electrides: Interstitial Electrons as Key Drivers of Multifunctional Properties and Applications

Advanced Science, EarlyView.
Eight AB‐type 2D inorganic electrides with negatively charged transition metals are theoretically designed. Their monolayers exhibit intrinsic magnetic ordering, rich topological phases, and ultralow work functions. Supported metal Ru on these 2D inorganic electrides effectively alleviates hydrogen poisoning and enables efficient ammonia synthesis ...

Effects of Strain Channel on Electron Irradiation Tolerance of InP-based HEMT Structures

Yuanzineng kexue jishu, 2023
The introduction of strain InxGa1-xAs channel with high In content increases the confinement of the two-dimensional electron gas (2DEG) and further improves the high-frequency performance of InGaAs/InAlAs/InP HEMTs.

Extrinsic and Intrinsic Charge Transfer at Interfaces of Membrane‐Based Oxide Heterostructures

Advanced Electronic Materials, EarlyView.
Freestanding oxides have emerged as a new opportunity to tailor oxides outside of the typical epitaxial constraints. We present the fabrication of TiO2‐terminated SrTiO3 membranes via direct growth control. We demonstrate competing ionic and electronic charge transfer in LaAlO3/SrTiO3 bilayers using near ambient pressure XPS.

Long‐Range Interactions in Topological Superconducting Systems: A Mini Review

Advanced Physics Research, EarlyView.
Long‐range interacting quantum systems are surveyed in this review, with an emphasis on the long‐range topological superconductor and its variants. Long‐range interactions decaying in a power‐law manner can lead to exotic phenomena that finds no analogue in short‐range regimes.

Electrical spin injection and detection in high mobility 2DEG systems

, 2016
In this review paper we present the current status of research related to the topic of electrical spin injection and detection in two-dimensional electron gas (2DEG) systems, formed typically at the interface between two III–V semiconductor compounds. We

Active SAW devices on 2DEG heterostructures

Electronics Letters, 2004
Active surface acoustic wave filters with voltage-controlled insertion losses have been achieved using AlGaN/GaN 2DEG heterostuctures as piezoelectric substrates. Transfer control is performed by moderate DC voltages between the fingers in either or both input and output interdigital transducers.

Assessing relational values of sacred landscapes through text mining of folktales: Insights from the Ryukyu Islands, Japan

People and Nature, EarlyView.
Abstract Assessing relational values of nature through its cultural and spiritual significance is crucial for effective nature conservation. Folktales offer insights into traditional relationships between people and nature, and text mining is a powerful tool for extracting information from textual datasets.

Japanese Women's Attitudes Toward Learning Languages Other Than English in the Era of Global English

International Journal of Applied Linguistics, EarlyView.
ABSTRACT This study on female Japanese learners of the Korean language is situated in the centuries‐long anti‐Korean sentiments in Japan, the global popularity of the Korean Wave, particularly among women, and the essentialized image of socially marginalized young Japanese women who study English with romantic desires for Western men.
