Scripts, Tutorials and Applications / how to construction multilayer's graphene (1-5layers) based on a gold electrode

« on: December 10, 2009, 10:26 »

Dear friends of the forum,


The following is the monolayer graphene script:
------------------------------------------
armchair = False   # False -> zigzag
width = 10        # ribbon width across, number of layers (must be even for zigzag)
repetitions = 10    # repetitions of the minimal unit along the ribbon
PAC = True         # False -> molecule

# C-C and C-H and unit cell padding distances (all in Angstrom)
aCC = 1.42086
aCH = 1.101
cell_pad = 30.

---
----------------------------------------------------

so i want to know that how to construction multilayer's graphene (1-5layers) based on a gold electrode of two probe system .

Graphene:1-5layers including 10-20 atoms.
Thanks in advance.

Scripts, Tutorials and Applications / V-I Curve simulation of graphene

« on: December 8, 2009, 03:55 »

Dear friends of the forum,

i have finished V-I Curve experimental studies on a gold two probe system based on the multilayer's graphene (gate bias voltage :0V). Now i would like to do some simulation for the following structure: gold two probe system based on the multilayer's graphene ,which offering some simulation result for camparision. i want to do the V-I (voltage 0-0.2V,gate bias voltage :0V)AND R-T (Temperature 5k-500k)calculations. So who can give me some help or .vnl scripts.

Electrode Au length:200um,width:30um,distance between the electrode:10um
Graphene:monolayer, bilayer and trilayer,length:20um,width:6um

Thanks in advance.
