Dear Dr. Papior,

I appreciate your attention to this matter.

Sincerely yours,

[SIESTA-L] error from Transiesta calculating I-V characterisitc

2018-11-18 Por tôpico maryam jamaati
Dear Siesta users,

We are calculating the I-V characteristic of a hybrid structure. For zero
bias voltage Transiesta converges very fast. But for other bias voltages it
didn't
converge. We changed scf parameters and it converged. We increased number
of contour points. Now. scf converges but the code is still running and the
below error message appears. Also no TSHS file is created.

I would be pleased if one could help us to solve the problem.


SCF cycle converged after 898 iterations
ts-err-D: ij( 1273,  1273), M = 0.83772   , ew = 0.29574   , em = 0.32983
. avg_m = 0.34189E-04
ts-err-E: ij( 1138,  1138), M = -1.2121   , ew = 0.10506E-1, em =
0.12548E-1. avg_m = 0.18626E-05
transiesta: constant dEf = -0.1747E-02 eV
ts-err-D: ij( 1273,  1273), M = 0.80236   , ew = 0.34517   , em = 0.35972
. avg_m = 0.18146E-04
ts-err-E: ij( 1273,  1273), M = -1.1882   , ew = 0.12167E-1, em =
0.12680E-1. avg_m = 0.56860E-06
