Temperature dependent transport in nanotube bioconjugatcs

摘要：

Carbon nanotube (CNT) based bioconjugates are among the candidates for molecular level electronics. In this work,we have studied transport mechanism of single walled carbon nanotube (SWNT) -peptide nucleic acid (PNA) bioconjugates. Electrical conductivity of the bioconjugates was studied at temperatures ranging from 70K to 350K. Negative differential resistance (NDR) behavior was observed at almost all temperatures and conductivity was found to increase with increasing temperatures. NDR behavior can be attributed to alignment and misalignment of energy bands of SWNT and PNA under different voltages.
