| dc.description.abstract | In this thesis we investigate the physical properties of a Boron-Nitride NanoTube(BNNT), in particular
the electric conductivity of the nanotube. The nanotube connects two reservoirs of different salt
concentration. We applied a concentration gradient of Na+ and Cl− in the nanotube and studied
whether we could compare the conductivity of the nanotube to the conductivity of a conducting wire.
The method of the research was a simulation with the finite element method in COMSOL. We found
a surface conductivity constant gs = 2.3 · 103 S/(m^2)
and a bulk conductivity constant gb = −1.8 · 102
S/m for a BNNT with a regulated surface charge and a pH value of 5.5, in the regime where the
radius of the tube is larger then the Debye length. For a radius smaller then the Debye length gb was
varying too much to make a reliable prediction | |
