The ferroelectric field-effect transistor with negative capacitance
I. Luk'yanchuk, A. Razumnaya, A. Sené +2
Integrating ferroelectric negative capacitance (NC) into the field-effect transistor (FET) promises to break fundamental limits of power dissipation known as Boltzmann tyranny. How…
Gate-tunable electron interaction in high-κ dielectric films
Svitlana Kondovych, Igor Luk'yanchuk, Tatyana I. Baturina +1
The two-dimensional (2D) logarithmic character of Coulomb interaction between charges and the resulting logarithmic confinement is a remarkable inherent property of high dielectric…
Nondestructive method of thin film dielectric constant measurements by two-wire capacitor
Svitlana Kondovych, Igor Luk'yanchuk
We suggest the nondestructive method for determination of the dielectric constant of substrate-deposited thin films by capacitance measurement with two parallel wires placed on top…
Giant Nernst-Ettingshausen oscillations in Semiclassically strong magnetic fields
Igor A. Luk'yanchuk, Andrei A. Varlamov, Alexey V. Kavokin
We consider the Nernst-Ettingshausen (NE) effect in the presence of semiclassically strong magnetic fields for a quasi-two dimensional system with a parabolic or linear dispersion…
Lattice-Induced Double-Valley Degeneracy Lifting in Magnetic Field in Graphene
Igor A. Luk'yanchuk, Alexander M. Bratkovsky
We show that the recently discovered double-valley splitting of the low-lying Landau level(s) in the Quantum Hall Effect in graphene can be explained as perturbative orbital intera…
Dirac and Normal Fermions in Graphite and Graphene: Implications to the Quantum Hall Effect
Igor A. Luk'yanchuk, Yakov Kopelevich
Spectral analysis of Shubnikov de Haas (SdH) oscillations of magnetoresistance and of Quantum Hall Effect (QHE) measured in quasi-2D highly oriented pyrolytic graphite (HOPG) [Phys…
