ZnO/AlGaN Ultraviolet Light Emitting Diodes

, 2005
We report on the optical and electrical properties of n-ZnO/p/-AlGaN heterojunctions. Ga doped n-type ZnO layers were grown using chemical vapor deposition on Mg doped p-type AlGaN epitaxial layers. AlGaN epitaxial layers with 12 at.% Al were grown on 6H-

Modulation magnesium-doping in AlGaN/GaN superlattices

, 2000
Low resistivity of p-type Mg-doped AlGaN/GaN superlattices (SLs) is demonstrated. The resistivity of the SLs is less than 0.6 Omega .cm. and the measured hole concentration is higher than 1x10(18)cm(-3). The resistivity of SLs is much lower, and the hole

Understanding the trap-induced frequency dispersion in the C–V curve of AlGaN/GaN hetero-structure

This article investigates the trapping mechanism in AlGaN/GaN heterostructure. For our study, the traps within the AlGaN layer are introduced at the interface and near the interface of AlGaN/GaN, in the SILVACO TCAD tool.

Al‐Rich AlGaN Channel High Electron Mobility Transistors on Silicon: A Relevant Approach for High Temperature Stability of Electron Mobility

Advanced Electronic Materials
Ultrawide bandgap (UWBG) semiconductors offer new possibilities to develop power electronics. High voltage operation for the off‐state as well as high temperature stability of the devices in on‐state are required.

Current transport mechanism in graphene/AlGaN/GaN heterostructures with various Al mole fractions

AIP Advances, 2016
The current transport mechanism of graphene formed on AlxGa1−xN/GaN heterostructures with various Al mole fractions (x = 0.15, 0.20, 0.30, and 0.40) is investigated. The current–voltage measurement from graphene to AlGaN/GaN shows an excellent rectifying

Simulation of polarization effects in AlGaN/GaN heterojunction

, 2004
A method for introducing polarization effects in the simulation of GaN-based heterojunction devices is proposed. A delta doping layer is inserted at the interface of heterojunction and the ionized donors or acceptors act as polarization induced fixed ...

Electroreflectance spectra of AlGaN/AlN/GaN heterostructure

, 2008
Electroreflectance spectra of AlGaN/AlN/GaN heterostructures were measured at various biased voltages (Vdc). Strengths of the internal electric field in AlGaN (FAlGaN) were evaluated from periods of Franz-Keldysh oscillations (FKOs), which were observed ...

Women’s Rights and Gender Equality in Turkey| The Politicization of Rape as a Consequence of Western Modernity and Religious Conservatism: Competing Media Narratives on Gender

International Journal of Communication, 2020
Through a feminist critical discourse analysis of newspaper columns from both secular/nationalist and religio-conservative outlets, this article illustrates how the issue of increased violence against women—which was made visible by the murder and ...
