position of doped atoms ,mixalch

hi all

i try to dope ZnO with Mn and use mixalch input variables .
i interest position of doped atom ,

for example
i doped ZnO with Mn % 5 , abinit how to creat crysytal structure and what is position of doped atom .
if i used supercell , i know position of doped atoms

thank for help

memory using when abinit running is bigger than reported in

hi all i am calculating Mn doped ZnO (%1) and abinit was terminated out of memory (probably it was terminated by system for out of memory) , according log file. using of memory report that 200 Mb memory is enough for each dataset and i have 28 Gb memory . ********************************************...

how to see place dopend element that are placed by mixalch

Dear all

i am calculating Mn doped ZnO and used mixalch ( not supercell) .
i want to see crystal structure of doped and want to know where are Mn atoms .
how can i do that ?

thanks for help

Alain thank you for help

i will use it but i don't understand coordinate of basis atom


Zn 1/3 2/3 0
O 1/3 2/3 3/8
it is ok but why like this .

Zn is in originate and it's coordinate must be 0 0 0 and
Oxygen' coordinate 0 0 3/8 ( because its above Zn )
