Current-Controlled Negative Differential Resistance due to Joule Heating in TiO2
A. S. Alexandrov, A. M. Bratkovsky, B. Bridle +3
We show that Joule heating causes current-controlled negative differential resistance (CC-NDR) in TiO2 by constructing an analytical model of the voltage-current V(I) characteristi…
Molecular dynamics simulations of oxide memristors: crystal field effects
S. E. Savel'ev, A. S. Alexandrov, A. M. Bratkovsky +1
We present molecular-dynamic simulations of memory resistors (memristors) including the crystal field effects on mobile ionic species such as oxygen vacancies appearing during oper…
Molecular dynamics simulations of oxide memristors: thermal effects
S. E. Savel'ev, A. S. Alexandrov, A. M. Bratkovsky +1
We have extended our recent molecular-dynamic simulations of memristors to include the effect of thermal inhomogeneities on mobile ionic species appearing during operation of the d…
Molecular dynamics simulations of oxide memory resistors (memristors)
S. E. Savel'ev, A. S. Alexandrov, A. M. Bratkovsky +1
Reversible bipolar nano-switches that can be set and read electronically in a solid-state two-terminal device are very promising for applications. We have performed molecular-dynam…
Key pairing interaction in layered doped ionic insulators
A. S. Alexandrov, A. M. Bratkovsky
A controversial issue on whether the electron-phonon interaction (EPI) is crucial for high-temperature superconductivity or it is weak and inessential has remained one of the most…
Polarons in 2+epsilon dimensions and giant figure of merit of semiconducting nanolayers
A. S. Alexandrov, A. M. Bratkovsky
Polarons - electrons coupled with lattice vibrations - play a key role in the transport and optical properties of many systems of reduced dimension and dimensionality. Their confin…
