Dear all,

 

I am working on transistors with K as dopant.

I am using GGA, PBE with the PSF files downloaded from the link
http://icmab.cat/leem/siesta/Databases/Pseudopotentials/periodictable-intro.
html

 

On running SIESTA I come across an error. 

For each atomic elements (for example "S")I use, the SIESTA generates
S.POT.CONF file and in the .out file it shows as :

 

atom: Called for S   (Z =  16)

 

read_vps: Pseudopotential generation method:

read_vps: ATM 3.2.2 Troullier-Martins

 

read_vps: Valence configuration (pseudopotential and basis set generation):

3s( 2.00) rc: 1.63

3p( 4.00) rc: 1.76

3d( 0.00) rc: 1.94

Total valence charge:    6.00000

 

xc_check: Exchange-correlation functional:

xc_check: GGA Perdew, Burke & Ernzerhof 1996

V l=0 = -2*Zval/r beyond r=  1.5917

V l=1 = -2*Zval/r beyond r=  1.7157

V l=2 = -2*Zval/r beyond r=  1.8962

All V_l potentials equal beyond r=  1.8962

This should be close to max(r_c) in ps generation

All pots = -2*Zval/r beyond r=  1.8962

 

VLOCAL1: 99.0% of the norm of Vloc inside     12.073 Ry

VLOCAL1: 99.9% of the norm of Vloc inside     27.515 Ry

atom: Maximum radius for 4*pi*r*r*local-pseudopot. charge    2.28723

atom: Maximum radius for r*vlocal+2*Zval:    1.99338

GHOST: No ghost state for L =  0

GHOST: No ghost state for L =  1

GHOST: No ghost state for L =  2

 

And so on . however, for "K", 

 

atom: Called for K   (Z =  19)

 

read_vps: Pseudopotential generation method:

read_vps: ATM3      Troullier-Martins

read_vps: Pseudopotential includes a core correction:

xc_check: Exchange-correlation functional:

V l=1 = -2*Zval/r beyond r=  4.6788

All V_l potentials equal beyond r=  2.9462

This should be close to max(r_c) in ps generation

All pots = -2*Zval/r beyond r=  4.6788

Using large-core scheme for Vlocal

 

atom: Estimated core radius    4.67876

atom: Maximum radius for 4*pi*r*r*local-pseudopot. charge    5.04317

atom: Maximum radius for r*vlocal+2*Zval:    4.73761

GHOST: No ghost state for L =  0

GHOST: WARNING: Ghost state for L =  1

KBgen: WARNING: Ghost states have been detected

KBgen: WARNING: Some parameter should be changed in the

KBgen: WARNING: pseudopotential generation procedure.

What's the reason for this? Am I using some a wrong PSF? Please help me out.

Thanks in advance.

 

Best,
