# GRID
# For 1D, z-axis is choosen

# REGIONS
# Region input is a two-dimensional list input.
# An example:
# Si p-n diode. Firstly lets picturize the regional input.
#         | Thickness (nm) | Material | Alloy fraction | Doping(cm^-3) | n or p type |
# Layer 0 |      250.0     |   Si     |      0         |     1e16      |     n       |
# Layer 1 |      250.0     |   Si     |      0         |     1e16      |     p       |

# To input this list in Gallium, we use lists as:
material =[[ 20.0, 'AlGaAs', 0.3, 1e17, 'n'],
           [ 50.0, 'GaAs', 0, 0, 'n']]
