Title: it is the channel too short to make PLDOS of p-i-n junction looks like that
Post by: njuxyh on February 20, 2019, 08:52

Hi :
recently, i have plot a PLDOS of P-i-N  junction model, and found the pictures look like  that :
i guess it is the too short channel length or too heavily doped on N region or p region? THANKS VERY MUCH IF SOMEONE COULD HELP ME

The PLDOS shows clearly that the channel is too short. The PLDOS should be flat in the vicinity of the left and right boundaries. See, e.g., Fig. 1 in PHYS. REV. APPLIED 10, 014026 (2018).

Best regards,
