We investigated the data transmission performance of indium antimonide (InSb) nanowires (NWs) synthesized on InSb (100) substrate using chemical vapor deposition (CVD) having diameters of 20 nm and below. The results indicate that the data transmission performance of NWs suffer from low mobility values on the order of 10-to-15 cm2V-1s-1 because of the scattering due to their small diameters, crystal defects and oxidation occurs during growth and cooling. The 20 nm NWs can sustain data rates up to 5 mega bits per second (Mbps) without any impedance matching and de-embedding of the parasitic parameters coming from the measurement system with a bit error rate (BER) level of 10-8. The data rate is directly proportional to the diameter of the NWs.
