Abstract EN
The electrical transport properties of individual Mg doped GaAs nanowires are investigated.
It is shown that Mg can be successfully used as a nontoxic p-type dopant in GaAs nanowires.
The doping levels, expanding over two orders of magnitude, and free holes mobility in the NW were obtained by the analysis of field effect transistors transfer curves.
The temperature dependence of the electrical resistivity above room temperature shows that the polytypic structure of the NWs strongly modifies the NWs charge transport parameters, like the resistivity activation energy and holes mobility.
At lower temperatures the NWs exhibit variable range hopping conduction.
Both Mott and Efros-Shklovskii variable range hopping mechanisms were clearly identified in the nanowires.
