It is exciting how nature varies when dimensionality changes. In my research I focus on the matter in D = 1.
Carbon nanotubes (CNT) was discovered to be extremely stable material of this dimensionality [S.Iijima, (7 November 1991). "Helical microtubules of graphitic carbon". Nature 354 (6348): 56–58]. CNT have a range of unique properties and are intesively studied for they give us a promise and hope for new exciting applications in nanotechnology.
Human's abilitity to complicate the matter has come to fruition this time, when nanocavities of CNT have been exploited in synthesis of 1D crystals [See e.g. C.E. Giuska et al, (2013) "Confined Crystals of the Smallest Phase-Change Material". Nano Lett. 13 (9): 4020–4027].
This extends the challenging field of research, where my current goal is to answer the questions:
- Can confinement of CNT be used for manipulation of state of the embedded materials?
(within EPSRC project "New modelling capabilities for nano-confined phase-change materials" with D.Quigley, J.Sloan from University of Warwick and A.Morris, P.Medeiros, J.Wynn from University of Cambridge)
- How does electron-phonon interaction change thermal conductivity of materials in 1D?
- Does anharmonic phonon-phonon scattering have positive effects on electron transport?
You might want to know what other questions scientists ask themselves.
Maybe you have an interesting unresolved question?
