[DFTB-Plus-User] R: R: negf calculation

[Theodoros Leontiou]

Dear Alessandro,
I have downloaded the version at the dftb+ website and used the examples
also found there.
These is the same format also discussed at dftb+
recipeshttp://www.dftbplus.org/fileadmin/DFTBPLUS/public/recipes-negf/html/index.html

I will download and try the beta version as you suggested.

Thanks

	Hi,
	I think you are using an old version of the manual or I really have to
look at it (!)
	The definition of the Transport block is outdated.
	You should move FermiLevel in each contact block as well as Potential (one
per contact).

	The energy range must be specified in the block 

	Analysis{ 

	   TunnelingAndDos{ …here… } 

	}
	What version of the code are you using? 

	You could download and test the beta version from github:
	https://github.com/aradi/dftbplus (https://github.com/aradi/dftbplus)
	there is a parallel-negf branch we are currently merging for a forthcoming
official release. 

	We are happy if you can test it and report problems.

	Again many thanks for your help!

	Hi,
	 If I interpret correctly the problem is that the Geometry{} block has
been removed in newest versions, so please remove it from your input. The
parser expects Device in the Transport block.
	Thanks for signaling this problem.
	Regards,
	Alessandro

Oggetto: [DFTB-Plus-User] negf calculation 

Dear dftb+ specialist
	I am trying to do my first dftb+ negf calculation.
	However, I get an error I don't know how to resolve. 
	I am running a test using the input files provided for the Silicon
nanowire 
	example. When I try to calculate the contact hamiltonian I get the
	following:
	ERROR!
	-> Missing child: Device
	Path: dftb_in/Transport
	Line: 6-23 (File: dftb_in.hsd)
	What is the meaning of the above error message?
	I am grateful for your help
	Regards
	Theodoros
	ps: I am attaching my input file below
