The most effective method, BD-method (combination of blending and dipping), is reported for increasing the conductivity of PEDOT:PSS using sodium dodecyl sulfate and the Joule heating behaviour of the fabric heater is demonstrated.

A room‐temperature HNO 3 treatment method is developed that significantly enhances the conductivity of a poly(3,4‐ethylenedioxythiophene):poly(4‐styrenesulfonate) (PEDOT:PSS) film, which is one of the most promising transparent conducting materials. The PEDOT:PSS film treated with HNO 3 exhibits a conductivity as high as 4100 S cm −1 , which is the highest value among reported conductivities achieved by treatments at room temperature. The mechanism of this conductivity enhancement is elucidated

The materials characteristics of Al2O3 films grown on a Si (100) substrate by traveling wave reactor atomic layer deposition were investigated in the growth temperature ranging from 250 to 500 °C. The Al2O3 films grown using Al(CH3)3 trimethylaluminum (TMA) and H2O as precursors were characterized and also compared with the films grown using AlCl3 and H2O. Both samples grown with different precursors revealed identical chemical binding state of oxidized Al and very flat surface morphology. In th

The passivation of organic light-emitting diodes (OLEDs) with Al2O3 films containing small amounts of N (Al2O3:N) was investigated by plasma-enhanced atomic layer deposition using a direct rf plasma with a short pulse time. Luminance—voltage and current density—voltage curves of an OLED passivated with a 300nm Al2O3:N film at 60°C remained unchanged compared to those of nonpassivated OLED and 96% of the initial luminance were maintained even after operating for 850h at 14mA∕cm2. The lifetime of

Two-dimensional transition metal dichalcogenides (TMDCs) have emerged as promising materials for next-generation electronics due to their excellent semiconducting properties. However, high contact resistance at the metal-TMDC interface plagues the realization of high-performance devices. Here, an effective metal-interlayer-semiconductor (MIS) contact is demonstrated, wherein an ultrathin ZnO interlayer is inserted between the metal electrode and MoS₂, providing damage-free and clean i

최근 한국에서는 저탄소 녹색성장이 새로운 국가발전 패러다임으로 제시되 고 녹색성장이란 용어가 유행어처럼 확산되고 있다. 이 글에서는 녹색성장 개념의 이념적 기초를 살피기 위해 이제껏 국제사회에서나 우리 사회에서 지배적인 담론 으로 부상한 “지속가능한 발전” 개념과 “생태 근대화”와 비교 분석하여 이 두 개 념과 어떠한 관계에 있는지 이론적으로 평가한다. 그리고 정부가 추진 중이거나 추진 예정인 다양한 사업들에 대한 검토와 분석을 통해 실제로 녹색성장 개념이 어느 정도 진정성 있게 추구되고 있는지 확인한다. 그 결과 저탄소 녹색성장 개념 은 성장지상주의적 본질을 내포하여 지속가능한 발전 개념의 가치를 담아내지 못 하는 하위 개념으로서 지속가능한 발전 개념을 폐기하거나 대체할 수 없으며 이 를 실현하기 위해서는 지속가능한 발전 개념을 보다 큰 틀 속에 위치시키면서 녹 색경제를 지향하는 하위 전략으로 추진되어야 함을 알 수 있었다. 녹색성장 개념 을 생태근대화론에 비교해보면 경제성장과 환

Even though climate change is visibly proceeding and public concern about climate change is increasing both nationally and internationally, teenagers' and students' perception of climate change is relatively low in Korea. Since climate change is a problem with long-term effects, it is young people including children and juveniles of the current generation and future generations who are more affected by climate change. They are the most interested party who should know why climate change happens,

Very uniform films could be deposited on polyethersulfone (PES) by plasma-enhanced atomic layer deposition (PEALD) using as O-precursor at temperatures ranging from 90 to 150°C. Although the use of rf plasma was prone to induce bending of the plastic substrate, lowering rf power and deposition temperature could eliminate the bending of the PES substrate in PEALD of an layer. At 100°C, films were deposited successfully by PEALD with 0.3 s rf pulse width and 300 W, with no measurable bending of su

Highly uniform films were deposited by plasma enhanced atomic layer deposition (PEALD) using tetrakis(ethylmethylamino)zirconium (TEMAZ) and as precursors. The deposition rates were 0.14 and 0.11 nm/cycle at temperatures of 110 and 250°C, respectively. films deposited at 150°C contained nitrogen, incorporated from the Zr-precursor, which contains four amino-groups. In the absence of a plasma, a film was not deposited with TEMAZ and at 150°C. The electrical characteristics including breakdown str

A policy network analysis using a questionnaire survey was conducted to identify the main climate policy actors in South Korea and examine how they form alliances and come into conflict over four major issues. Generally, it was found that governmental organizations are the main actors in the South Korean climate policy arena and that they mediate between the business and civil sectors. In particular, key organizations in each sector play a leading role in the formation and maintenance of at leas

Residential electricity consumption is steadily increasing in Korea, whose carbon emissions from fuel combustion are ranked 7th globally. However, various social variables that affect electricity demand have changed in recent years, and there are many differences in local distribution. This study analyzed electricity consumption factors in 225 Korean municipalities from 2010 to 2019, using a spatial panel model to reflect local characteristics and temporal differences in social variables. The st

Although the deployment of wind energy has gradually increased in South Korea, local opposition to the development of wind projects has frequently been reported; this could retard the deployment of wind power in South Korea. Noise from the operation of wind turbines is claimed to be the major reason for opposition. This study explored factors related to local residents’ attitudes toward adjacent wind farms and the noise annoyance associated with them. Multivariate linear regression models were a

The CaS:Pb phosphor emitting blue electroluminescence (EL) induced by dimeric Pb2+ luminescent centers was deposited using the controlled atomic layer deposition technique. The effect of the incorporation method and concentration of Pb2+ ions on the color of high luminance CaS:Pb phosphor was investigated at the deposition temperatures of 350 and 400 °C. The blue EL emission at 440–445 nm could be maintained with the Pb concentration ranging from 0.6 to 2.5 mol % contrary to the earlier works th
