英文摘要	An increase of work function (0.3 eV) is achieved by irradiating poly(3,4-ethylenedioxythiophene): poly(styrene sulfonate) (PEDOT: PSS) film in vacuum with 254-nm ultraviolet (UV) light. The mechanism for such an improvement is investigated by photoelectron yield spectroscopy, X-ray photo electron energy spectrum, and field emission technique. Surface oxidation and composition change are found as the reasons for work function increase. The UV-treated PEDOT: PSS film is used as the hole injection layer in a hole-only device. Hole injection is improved by UV-treated PEDOT: PSS film without baring the enlargement of film resistance. Our result demonstrates that UV treatment is more suitable for modifying the injection barrier than UV ozone exposure.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000335646100097&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Physics, Multidisciplinary; SCI(E); EI; 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 4; ARTICLE; xingyj@pku.edu.cn; 3; 23
