Improved deposition of ZnO:Ga thin films by sputtering with the chamber pressure
Journal of the Korean Physical Society - Tập 83 - Trang 867-872 - 2023
Characteristics of ZnO:Ga (GZO) thin films fabricated by RF magnetron sputtering using chamber pressure have been investigated. Low chamber pressure results in low resistivity due to high mobility and carrier concentration. Result is ascribed to minimizing the influence of residual gases in the chamber, which promotes stoichiometric composition, increases Ga concentration and reduces grain boundar...... hiện toàn bộ
A theoretical approach to study the thermal impact of the DC and RF characteristics of a MgZnO/ZnO HEMT
Journal of the Korean Physical Society - Tập 84 - Trang 313-322 - 2024
In this work, a new current model of the MgZnO/ZnO high electron mobility transistors (HEMTs) has been developed considering the exact velocity-field characteristics of electrons in ZnO. The drain current of the device has been studied with reference to different applied potentials. The other device parameters, such as drain conductance, mutual conductance, cut-off frequency, and maximum operating...... hiện toàn bộ
Entropy Generation Minimization in MHD Boundary Layer Flow over a Slendering Stretching Sheet in the Presence of Frictional and Joule Heating
Journal of the Korean Physical Society - Tập 73 - Trang 1303-1309 - 2018
In the present paper, we study the entropy analysis of boundary layer flow over a slender stretching sheet under the action of a non uniform magnetic field that is acting perpendicular to the flow direction. The effects of viscous dissipation and Joule heating are included in the energy equation. Using similarity transformation technique the momentum and thermal boundary layer equations to a syste...... hiện toàn bộ
Half-metallicity in a new Heusler alloy Ti2FeSn: A density functional study
Journal of the Korean Physical Society - Tập 64 - Trang 277-282 - 2014
First-principles calculations based on density functional theory for a new Heusler compound Ti2FeSn have been performed using the self-consistent full-potential linearized augmented plane wave method. The results showed that the Ti2FeSn Heusler alloy was a half-metallic ferrimagnet. The obtained total magnetic moment of Ti2FeSn was 2 μ

Neutron Detection Using a Gadolinium-Cathode Gas Electron Multiplier Detector
Journal of the Korean Physical Society - Tập 76 - Trang 961-966 - 2020
A gas electron multiplier (GEM) detector with a gadolinium cathode has been developed to explore its potential application as a neutron detector. It consists of three standard-sized (10 × 10 cm2) GEM foils and a thin gadolinium plate as the cathode, which is used as a neutron converter. The neutron detection efficiencies were measured for two different cathode setups and for two different drift ga...... hiện toàn bộ
Nanopattern fabrication via AP-UVO exposure of a self-organized block copolymer
Journal of the Korean Physical Society - Tập 60 - Trang 501-504 - 2012
Block copolymers were used to achieve nanoscale patterning. Block copolymers, particularly polystyrene-block-poly(methyl methacrylate) (PS-b-PMMA), produce patterns from which one block polymer may be selectively etched. However, the selective wet etching of PMMA with acetic acid can induce the remaining PS structures to collapse due to capillary forces between adjacent PS domains during drying. T...... hiện toàn bộ
Study of the Structural, Elastic, Electronic and Optical Properties of the Ternary Acetylides A2MC2 (A = Na, K) and (M = Pb, Pt)

Dielectric Functions and Critical Points of GaAsSb Alloys
Journal of the Korean Physical Society - Tập 74 - Trang 595-599 - 2019
We report the pseudodielectric functions and the critical points of GaAsxSb1−x ternary alloy films. Data were obtained by performing spectroscopic ellipsometry on 1-μm-thick films grown on (001) GaAs by using molecular beam epitaxy. Artifacts from surface contaminants, including oxide overlayers, were minimized by using in-situ chemical cleaning, leading to accurate representations of the bulk die...... hiện toàn bộ
Comparison of pencil-beam, collapsed-cone and Monte-Carlo algorithms in radiotherapy treatment planning for 6-MV photons
Journal of the Korean Physical Society - Tập 67 - Trang 153-158 - 2015
Treatment planning system calculations in inhomogeneous regions may present significant inaccuracies due to loss of electronic equilibrium. In this study, three different dose calculation algorithms, pencil beam (PB), collapsed cone (CC), and Monte-Carlo (MC), provided by our planning system were compared to assess their impact on the three-dimensional planning of lung and breast cases. A total of...... hiện toàn bộ
