Solvetimestep2D

$solvetimestep2D is a command for solving the transient behavior of the device. The format is

$solvetimestep2D
number_of_different_steps(Nt)
steptype contact_type  $δ t t_{t o t a l}$  par1 par2 par3 par4 ....    
steptype contact_type  $δ t t_{t o t a l}$  par1 par2 par3 par4 ....    
...
steptype contact_type  $δ t t_{t o t a l}$  par1 par2 par3 par4 ....    repeat Nt times

The number of parameters depeding on step type. Now we have 3 step types

Steptype  = 1:  

 $δ t, t_{t o t a l}, v g_{0}$ 

 vg=vg_end for t<0, for t>0, vg= $v g_{0}$

Steptype  = 2:  

 $δ t, t_{t o t a l}, v g_{0}, A_{0}, ω, c_{0}$ 

 $v g = v g_{0} + A_{0} \times s i n (2 π ω t + c_{0})$

Steptype  = 3:  

 $δ t, t_{t o t a l}, v g_{0}, A_{0}, ω, c_{0}$ 

 $v g = v g_{0} + i n t (A_{0} \times s i n (2 π ω t + c_{0}))$

contact_type

2: gate
3: source
4: drain

For example:

$solvetimestep2D
2
2 2 1.0e-10 1.0e-6 3.00 0.1 1.0e6 0.0 
2 4 1.0e-10 1.0e-6 3.00 0.1 1.0e6 0.0 
  $v g = 3.0 + 0.1 \times s i n (2 π \times 1 0^{6} t)$ 

  $v d = 3.0 + 0.1 \times s i n (2 π \times 1 0^{6} t)$
