A Review of Recent Research Advances on AlGaN-Based Deep Ultraviolet Light-Emitting Diodes

IEEE Access
Due to environmental friendliness, small size, long lifetime, and adjustable light-emitting wavelength, AlGaN-based deep ultraviolet light-emitting diodes (DUV-LEDs) have great development potential in the fields of biochemical detection, sterilization ...

From Inner Capacities to Global Outcomes: Social–Emotional Capital as a Driver of SDG Performance

Sustainable Development, EarlyView.
ABSTRACT Despite unprecedented global commitment to the 2030 Agenda, progress toward the sustainable development goals (SDGs) continues to lag in ways that structural, institutional, and resource‐based explanations do not fully explain. This study argues that a critical missing dimension is human: the psychological and relational capacities that enable

High‐Performance Self‐Powered Perovskite Photodiodes for Blue‐Light Detection Using Anisole‐Assisted Precursor Engineering

Small, EarlyView.
Anisole‐assisted precursor engineering provides a simple route to high‐quality perovskite films for self‐powered blue‐light photodetection. Anisole promotes grain growth and suppresses pinholes, reducing dark current while improving external quantum efficiency and detectivity.

Why Does Individualism Affect Economic Development: Is It Values, Policies, or Institutions?

Southern Economic Journal, EarlyView.
ABSTRACT A substantial body of literature highlights the positive roles of individualism and economic freedom in fostering prosperity, and recent work links the two. This paper disentangles their contributions to economic development. In cross‐country data, we show that both are independently associated with per capita income, even after extensive ...

Ethnic Groups' Access to State Power and Group Size

Economics &Politics, EarlyView.
ABSTRACT Ethnic‐based political inequality is widespread, yet its underlying drivers remain poorly understood. This paper shows that an ethnic group's relative size is a key correlate of its access to central executive power. Using data on 575 groups across 181 countries from 1946 to 2021, and restricting attention to non‐dominant groups, I document a ...

Low-frequency noise in AlTiO/AlGaN/GaN metal-insulator-semiconductor heterojunction field-effect transistors [PDF]

, 2016
Using aluminum titanium oxide (AlTiO, an alloy of Al_2O_3 and TiO_2) as a high-k gate insulator, we fabricated and investigated AlTiO/AlGaN/GaN metal-insulator-semiconductor heterojunction field-effect transistors.

Associations Between Imaging‐Detected Pulp Calcification and Systemic Diseases: A Systematic Review, Thematic Analysis, and Meta‐Analysis

International Endodontic Journal, EarlyView.
ABSTRACT Background Pulp calcification (PC) is a common imaging finding traditionally attributed to local factors or ageing. However, increasing evidence suggests that it may be associated with broader systemic biological disturbances. Clarifying this association may help determine whether dental pulp findings contribute to the interpretation of ...

Less Happy, Though More Educated: What Explains Lower Life Satisfaction Among Highly Educated First‐Generation Immigrants in Highly Prosperous Countries?

International Social Science Journal, EarlyView.
ABSTRACT Conventional wisdom suggests that higher education (HE) and national prosperity (or wealth) contribute to improved life satisfaction. Is this also true for first‐generation immigrants? Using multilevel models on 16,368 individuals across 35 European countries from the European Social Survey, the results demonstrate that, although immigrants ...

AlGaN/GaN HEMTs With Thin InGaN Cap Layer for Normally Off Operation [PDF]

, 2007
AlGaN/GaN HEMTs with a thin InGaN cap layer have been proposed to implement the normally off HEMTs. The key idea is to employ the polarization-induced field in the InGaN cap layer, by which the conduction band is raised, which leads to the normally off ...

Temperature Dependence of the Energy Band Diagram of AlGaN/GaN Heterostructure

Advances in Condensed Matter Physics, 2018
Temperature dependence of the energy band diagram of AlGaN/GaN heterostructure was investigated by theoretical calculation and experiment. Through solving Schrodinger and Poisson equations self-consistently by using the Silvaco Atlas software, the energy
