今天主要解决一下defect语句:
defect region=1 nta=1.55e20 wta=0.013 wtd=0.12 ngd=6.5e16 wga=2 ntd=1.55e20 ngd=0 wgd=0
之前(02)的例子里还有doping的定义:
doping material=IGZO donor concentration=5e17 uniform
doping前:
doping后:
???可能是掺杂多了???
这篇文章里给出了IGZO部分参数:
语句更改如下:
material material=igzo eg300=3.5 nc300=5e18 nv300=4.5e21 taun0=1e-9 taup0=1e-9 affinity=4.16 mup=0.1 mun=15 defect region=1 nta=1e18 wta=0.013 wtd=0.12 ngd=6.5e14 wga=2 ntd=4.5e21 ngd=0 wgd=0 interface QF=-2e10 S.I
输出:(-16~-6)
接下来安排:
1.阅读文献,深度理解DOS模型的含义;
2.调试,寻找参数与开关比的关系,调整开关电流;

输出:
放大,关注的开态电流:
主要变化还是依据于迁移率mun参数的改变,根据文献,开态饱和电流公式:
直接更改的参数只有迁移率与栅电容,但是迁移率有限制,即IGZO迁移率仍存在限制。下一步考虑更改氧化层参数。
