Abstract: In this study, the electron transport was calculated as a function of the width of the two dimension Germanene structures using Gollum program. We showed good relax of Germanene structures was obtained using GGA/DZP-DFT at SIESTA-trunk-462 of program. Electrical and thermal conductivity of the studied Germanene structures have been studies. The shape of the Germanene structure play a significant role in electrical and thermal conductivity calculations. I-V curve showed the Germanene structures have characters similar to the sensing type. These results of nanostructures offer that a suitable contact with the two electrodes have quite limited effect on the sensing behavior of the structures and this from the lowering of the energy gap between the HOMO of the structure and the Fermi level of the electrode in the forward and reverse bias.
