General Questions and Answers / I want to know the electrode correspondence in the PN junction diode.
« on: July 16, 2024, 05:49 »
In the 2022-12-sp1 version, the D and S electrodes corresponded to the left and right electrodes during the PN junction, respectively. However, in the 2023-12-sp1 version, the electrode correspondence is reversed, i.e. the left electrode corresponds to S and the right electrode corresponds to D. This results in opposite I-V curves for the two versions under the same calculation script. I wonder which version is the right one.
In addition, in version 2023-12-sp1, the bias defined in the I-V curve script is Vds=Vd-Vs, and Vs is set to 0, while the bias is still set by subtracting the right electrode from the left electrode in DeviceLCAOCalculator, which may means Vs-Vd. I wonder if there is a conflict between these two? Or am I misunderstanding what it means?
