Quantum point contact due to Fermi-level pinning and doping profiles in semiconductor nanocolumns
We show that nanoscale doping profiles inside a nanocolumn in combination with Fermi-level pinning at the surface give rise to the formation of a saddlepoint in the potential profile. Consequently, the lateral confinement inside the channel varies along the transport direction, yielding an embedded quantum point contact. An analytical estimation of the quantization energies will be given.
متن کاملPropagative Landau states and Fermi level pinning in carbon nanotubes.
We present strong evidence of Landau states formation in multiwalled carbon nanotubes with metallic or semiconducting outer shells, under magnetic fields as high as 60 T. Magnetoconductance data are found to converge to a gate-independent value for semiconducting shells, whereas for metallic shells, the Landau states introduce a strong reintroduction of backscattering and Fermi level pinning cl...
متن کاملSurface recombination, surface states and Fermi level pinning
2014 Surface and interface recombination processes, which are becoming more and more important with the appearance of small-size optoelectronic devices, are still not well understood because reliable data are very scarce. We report here the first simultaneous in situ measurements of the density and position of surface states, of the position of the Fermi level at the surface, and of the surface...
متن کاملFermi-level pinning can determine polarity in semiconductor nanorods
First-principles calculations of polar semiconductor nanorods reveal that their dipole moments are strongly influenced by Fermi-level pinning. The Fermi level for an isolated nanorod is found to coincide with a significant density of electronic surface states at the end surfaces, which are either mid-gap states or band-edge states. These states pin the Fermi level, and therefore fix the potenti...
متن کاملBand offsets and Fermi level pinning at metal-Al2O3 interfaces
Disparities between the predicted and the measured effective work functions (EWFs) in advanced metal oxide semiconductor devices, or Fermi-level pinning (FLP), have gained significant attention when high-k dielectrics began to emerge. Using a systematic approach for EWF extraction, combined with a comparison to unpinned SiO2 references, it was found that no intrinsic FLP exists in the model die...
