Theory of the Room-Temperature QHE in Graphene
Shigeji Fujita, Akira Suzuki
The unusual quantum Hall effect (QHE) in graphene is often discussed in terms of Dirac fermions moving with a linear dispersion relation. The same phenomenon will be explained in t…
Composite-particles (Boson, Fermion) Theory of Fractional Quantum Hall Effect
Shigeji Fujita, Akira Suzuki, H. C. Ho
A quantum statistical theory is developed for a fractional quantum Hall effects in terms of composite bosons (fermions) each of which contains a conduction electron and an odd (eve…
Theory of High-Field Transports in Metallic Single-Wall Nanotubes
S. Fujita, H. C. Ho
Individual metallic single-wall carbon nanotubes show unsual non-Ohmic transport behaviors at high bias fields. For low resistance contact samples, the differential conductance dI/…
On the Transport Diamonds and Zero Current Anomaly in InGaAs/InP and GaAs/AlGaAs
S. Fujita, H. C. Ho
In the quantum Hall effect (QHE) the differential resistivity vanishes within a range where the Hall resistivity forms a plateau. A microscopic theory is develope…
Theory of the Conductivity in Semiconducting Single-Wall Carbon Nanotubes
S. Fujita, S. Moon, Y. Takato +2
The conduction of a single-wall carbon nanotube depends on the pitch. If there are an integral number of carbon hexagons per pitch, then the system is periodic along the tube axis…
Quantum statistical model for superconducting phase in graphene and nanotubes
Shigeji Fujita, Rohit Singh, Salvador Godoy +1
A quantum statistical theory is presented, supporting a superconducting state of an ultrahigh critical temperature (1275 K) in the multiwalled nanotubes reported by Zhao and Beeli…
