p-n diode calculation result
« on: September 23, 2012, 17:20 »
Dear  QuantumWise team ,
 i have calculated the result of p-n diode in f-b mode. i have some doubt related the result of  p-n diode  diff. bais please see below

p-n diode ------ I-V CHARCRISTIC IN DIFF. BIAS

CASE -1 --------- 0.2V( LEFT ELECTRODE 0.1V, RIGHT ELECTRODE -0.1)
                       3.4105na (approx)
CASE-2-----------0.4V (0.2V, -0.2V)
                         5.45na APPROX
CASE -3-------------0.6V(0.3V,-0.3V)
                            7.38 na APPROX
CASE-4--------------0.8V(0.4V,-0.4V)
                             9.14 na APPROX
CASE-5--------------1.0(0.5V,-0.5V)
                               11.2 na APPROX
CASE-6--------------1.2(0.6V,-0.6V)
                            13.27 na APPROX
CASE-7---------------1.4(0.7V,-0.7V)
                              15.62 na APPROX

1    My Question is ,-------------- pn diode forward bias char. ( current is initially linear  after reaches the 0.6 approx( knee voltage )     current is suddenly  raised but in that case o have confused ......... please suggest me this correct or not  current value of different bias
                                                     please send me valuable answer of this question bcos it''s important for me?

2. I am using atk 12.2.0 version , please tell me how i  can calculated of band gap , dynamic capacitance of p-n diode  . i know that these answer are already posted on forum but when these all python script( band gap, dynamic capacitance) was  opening  in  ATK 12.2.0  , i have seen that error after that these file not open in atk12.2.0 . please suggest me what i can do.
