Unlike graphene, 3DTDS allows electrons to be assembled in a collective to flow in all directions. More important, the electrons on the surface of the material remember their magnetic spin, so data can be stored by reversing the polarity of a bit.

In the newly discovered materials, named '3D topological Dirac semimetals' (or 3DTDS in short), electrons can travel along any direction in its 3D bulk with energy linearly dependent on its momentum. Furthermore, the electrons in 3DTDS can race at much higher speeds than in silicon, which promises not only new physical insights, but also exciting applications for the high-tech industry such as much faster transistors and far more compact hard drives.

One of the best features of the 3DTDS carbon nanotube is that the electron will be essentially free of mass while travelling, so creating enough velocity and mobility will require even less energy input. At the same time, these materials are still difficult and costly to produce. Current projections have mainstream use and acceptance of these materials in 30 years or more.

Therefore, in principle, there is a critical value, x = x_c, at which a topological phase transition from 3DWTI to 3DTDS can take place.
