[SIESTA-L] Please, help with DENCHAR...

2009-07-28 Thread Руслан Жачук
Dear siesta users, as far as I understand the only tool capable to plot wave functions in Siesta is Denchar. Unfortunately I got following error during compilation and cannot proceed. This error is mentioned in mailing list archive, but I found no solution published. Please, help... Ruslan

Dear SIESTA users, can you help me to write request for resources for parallel run. It looks like when this request is incorrect the job stops. We are using PBS Pro 9.2 system. The request string looks like this: #PBS -l select=3:ncpus=3:mpiprocs=3:mem=6GB The system I am studying is Si slab

[SIESTA-L] simulated STM images (not LDOS)

2009-02-08 Thread Руслан Жачук
Dear SIESTA users, recently I found a paper Phys. Rev. Lett. 94 (2005) 056103 which describe new effective method to simulate realistic STM images. It is not just LDOS plot, the authors calculate wave fucntions of tip and surface independently and then simulate the current, assuming that tip

Re: [SIESTA-L] H-passivation

2008-12-23 Thread Руслан Жачук
You just set the H atom in the direction of Si bond at the distance, corresponding to the length of Si-H bond. As I remember it is approximately 1.5 Angstrom. Keep the coordinates of H atom and Si atom connected to it fixed during structure optimization. You don't need to relax them. Regards,

Dear SIESTA users, I need to model STM image of clean Si surface, i.e. to get LDOS. All important calculations I did in AIMPRO code and now I need only STM image, so the calculation does not need to be very accurate. I moved to SIESTA since AIMPRO has no STM utility. But I am new to SIESTA and
