Under the action of a positive gate bias stress,a hump in the subthreshold region of the transfer characteristic is observed for the amorphous indium-gallium-zinc oxide thin film transistor,which adopts an elevated-metal metal-oxide structure.As stress time goes by,both the on-state current and the hump shift towards the negative gate-voltage direction.The humps occur at almost the same current levels for devices with different channel widths,which is attributed to the parasitic transistors located at the channel width edges.Therefore,we propose that the positive charges trapped at the backchannel interface cause the negative shift,and the origin of the hump is considered as being due to more positive charges trapped at the edges along the channel width direction.On the other hand,the hump-effect becomes more significant in a short channel device (L =2 μm).It is proposed that the diffusion of oxygen vacancies takes place from the high concentration source/drain region to the intrinsic channel region.

奶奶生前信佛，便照佛教的规矩办了葬礼。没有哭声，家里只是请了穿着黄色袈裟的僧人，念经超度亡灵。 香火缭绕，木鱼一下一下地敲在我的心上。在来来往往的身影间，我竟影影綽绰地看到奶奶的影子。 奶奶也曾为别人念经祈福，不收报酬。只要别人有需求，她便笑着应承下来，往香炉里添一炷香。 每天晚上，奶奶都要将灰白稀疏的头发梳得服服帖帖，然后绾起来，插上一朵小蓝花。随后洗净手，添了香跪下来，开始念念有词：“愿

我早已对西塘心驰神往——古镇烟雨蒙蒙，青石板桥上苔痕依稀，河水潺潺流淌着，一切显得那么静谧、美好。淡淡的江南韵味就融在这漫长的时光里。 我结束幻想，直奔景区入口，迫不及待地想要去揭开我所憧憬的古镇面纱。 不！这不是西塘！ 我吃惊地瞪大了眼：入口处人潮涌动，排队的游客摩肩接踵;蜷缩在母亲怀抱里的孩子受不了这拥挤，大声哭闹起来;许多人的脸上显示出疲累。这喧闹的地方，是那个古色古香的小镇西塘吗？
上学期的早读课，张老师只安排徐哲祺一个人领读。因为开学第一天徐哲祺就表现突出，张老师一下子就记住了他。整整一个学期，我天天羡慕徐哲祺，心里想着：要是我也能站上讲台领读，那该多好啊！ 这个学期一开学，张老师就跟我们说：“要再增加一个人领读，大家觉得自己可以的先到我这儿来报名，然后我们公平竞选。”我一听到这个天大的好消息，就跃跃欲试了。经过一个学期的积累，我觉得自己能够胜任领读任务。 经过张老师的
晚秋，风乍起，红叶以及银杏叶不时飞舞着。白天，它们掠过窗前;晚上，则扑打着窗户。枫树露出枯瘦的枝丫，树梢上挂着几片残叶，地上一片火红。前几日的银杏叶还像一朵朵黄色的云，“飘荡”在高大的树上，今日却纷纷飘落，好似晚秋飞舞的黄蝶。 这个时节是极静谧的。清晨的白霜、傍晚的夕阳，无声无息地带走一片生机。对窗读书，四周静悄悄的，偶尔有晃动的影子映在百叶窗上。开门一望，院子里的桃树叶落了。西风打落梧桐叶，叶
