We fabricate pentacene-based organic field effect transistors(OFETs),inserting a transition metal oxide(V2 O5)layer between the pentacene and Al source-drain(S/D)electrodes.The performance of the devices with V2O5/AlS/D electrodes is considerably improved compared to the pentacene-based OFET with only Al S/D electrodes.After the 10-nm V2O5 layer modification,the effective field-effect mobility of the devices increases from 2.7 ×10-3 cm2 /V.s to 8.93 × 10-1 cm2 /V.s.Owing to the change of the injection property,the effective threshold voltage (Vth)is changed from-7.5 V to-5 V and the on/off ratio shifts from 102 to 104.Moreover,the dispersion of sub-threshold current in the devices disappears.These performance improvements are ascribed to the low carrier injection barrier and the reduction of contact resistance.It is indicated that V2O5 layer modification is an effective approach to improve pentacene-based OFET performance.

周末，闲极无聊，拉了朋友去逛街，走进一家家精品鞋城，各式各样的鞋子真是琳琅满目，直让人看花了眼。 突然，一双精巧而又别致的小布鞋映入了我的眼帘，它静静地被摆放在一个偏僻的角落里。平平的鞋跟，平纹的绣花呢子布料，宽宽的四方口，一根系扣的鞋带，像极了儿时曾经穿过的那些布鞋的样子。我情不自禁地走过去，拿起它仔细端详起来。恍惚中，母亲那在灯下做鞋的样子好像又浮现在了我的面前，一针针，一线线，密密地缝着。
