5.18出盲审结果，这几天都是起床就开着电脑跑仿真。
SAM-APD的sde语句，跟前一个语句差的不多，主要改了下p+厚度。本来想把掺杂浓度改成变量，想了想成功几率不大，也没什么用，就这样了：
;define parameter (define Ltot 10) ;total size of the device (define Hp+ 0.1 ) ;thickness of the p+ layer (define Hp 0.3 ) (define Hn 0.25 ) ;thickness of the n layer (define Hn- 1 ) ;thickness of the n- layer (define Hbu 0.5 ) ;thickness of the buffer layer (define Hsub 2 ) ;thickness of the substrate ;derived quantities x values of bottom layers (define Xsub (* Ltot 0.5)) ;y values of each bottom layers (define Yp+ Hp+) (define Yp (+ Yp+ Hp)) (define Yn (+ Yp Hn )) (define Yn- (+ Yn Hn- )) (define Ybu (+ Yn- Hbu)) (define Ysub (+ Ybu Hsub )) ; Overlap resolution: New replaces Old (sdegeo:set-default-boolean "ABA") ; Creating sub (sdegeo:create-rectangle (position (* Xsub -1.0) Ysub 0.0 ) (position Xsub Ybu 0.0 ) "SiliconCarbide" "region_1" ) ; Creating buffer layer (sdegeo:create-rectangle (position (* Xsub -1.0) Ybu 0.0 ) (position Xsub Yn- 0.0 ) "SiliconCarbide" "region_2" ) ; Creating n- (sdegeo:create-rectangle (position (* Xsub -1.0) Yn- 0.0 ) (position Xsub Yn 0.0 ) "SiliconCarbide" "region_3" ) ; Creating n (sdegeo:create-rectangle (position (* Xsub -1.0) Yn 0.0 ) (position Xsub Yp 0.0 ) "SiliconCarbide" "region_4" ) ; Creating p+ (sdegeo:create-rectangle (position (* Xsub -1.0) Yp 0.0 ) (position Xsub Yp+ 0.0 ) "SiliconCarbide" "region_5" ) (sdegeo:create-rectangle (position (* Xsub -1.0) Yp+ 0.0 ) (position Xsub 0.0 0.0 ) "SiliconCarbide" "region_6" ) (sdegeo:define-contact-set "anode" 4.0 (color:rgb 1.0 0.0 0.0 ) "##") (sdegeo:define-contact-set "cathode" 4.0 (color:rgb 0.0 1.0 1.0 ) "##") (sdegeo:define-2d-contact (find-edge-id (position 0.0 0.0 0.0)) "anode") (sdegeo:define-2d-contact (find-edge-id (position 0.0 Ysub 0.0)) "cathode") ; Separating lumps (sde:assign-material-and-region-names "all") (sdedr:define-constant-profile "const.sub" "NitrogenConcentration" 1e21) (sdedr:define-constant-profile-region "placeCD.sub" "const.sub" "region_1") (sdedr:define-constant-profile "const.n-" "NitrogenConcentration" 1e15) (sdedr:define-constant-profile-region "placeCD.n-" "const.n-" "region_3") (sdedr:define-constant-profile "const.n" "NitrogenConcentration" 4e17) (sdedr:define-constant-profile-region "placeCD.n" "const.n" "region_4") (sdedr:define-constant-profile "const.p" "AluminumConcentration" 1e18) (sdedr:define-constant-profile-region "placeCD.p" "const.p" "region_5") (sdedr:define-constant-profile "const.p+" "AluminumConcentration" 2e19) (sdedr:define-constant-profile-region "placeCD.p+" "const.p+" "region_6") (sdedr:define-constant-profile "const.buff" "NitrogenConcentration" 1e18) (sdedr:define-constant-profile-region "placeCD.buff" "const.buff" "region_2") ;build mesh (sdedr:define-refeval-window "RefWin.n3" "Rectangle" (position (* Xsub -1.0) Yn- 0.0) (position Xsub Yp 0.0)) (sdedr:define-multibox-size "RefDefMB.n3" 0.04 0.2 0.02 0.05 1 1.5 ) (sdedr:define-refinement-function "RefDefMB.n3" "DopingConcentration" "MaxTransDiff" 1 "DoubleSide") (sdedr:define-multibox-placement "PlaceMB.n3" "RefDefMB.n3" "RefWin.n3" ) (sdedr:define-refeval-window "RefWin.n5" "Rectangle" (position (* Xsub -1.0) Yp 0.0) (position Xsub (- Yp 0.1) 0.0)) (sdedr:define-multibox-size "RefDefMB.n5" 0.04 0.05 0.02 0.05 1 -1.5 ) (sdedr:define-multibox-placement "PlaceMB.n5" "RefDefMB.n5" "RefWin.n5" ) (sdedr:define-refeval-window "RefWin.n6" "Rectangle" (position (* Xsub -1.0) Yp 0.0) (position Xsub 0.0 0.0)) (sdedr:define-multibox-size "RefDefMB.n6" 0.04 0.2 0.02 0.05 1 1.5 ) (sdedr:define-multibox-placement "PlaceMB.n6" "RefDefMB.n6" "RefWin.n6" ) (sdedr:define-refinement-window "RefWin.n4" "Rectangle" (position (* Xsub -1.0) Ysub 0) (position Xsub Yn- 0)) (sdedr:define-multibox-size "RefDefMB.n4" 2 1 0.4 0.2 1 1.5 ) (sdedr:define-multibox-placement "PlaceMB.n4" "RefDefMB.n4" "RefWin.n4" ) (sdedr:define-refeval-window "RefWin.n7" "Rectangle" (position (* Xsub -1.0) Yn 0.0) (position Xsub Yp+ 0.0)) (sdedr:define-multibox-size "RefDefMB.n7" 0.04 0.2 0.02 0.05 1 -1.5 ) (sdedr:define-multibox-placement "PlaceMB.n7" "RefDefMB.n7" "RefWin.n7" ) (sde:build-mesh "snmesh" "" "n@node@_msh")仿真一个点就要一小时，试着调初始电压和步长调节时间，但还是不奏效。一个平面器件就要22个点，两个窗口形态，三个变量。22*16*10小时大概133天。
emmmmmmmm
祝我好运能毕业
