Settling the “Dead Layer” Debate in Nanoscale Capacitors
Advanced Materials, 2009Permittivity peaks in single crystal thin film capacitors are strongly suppressed compared to bulk in the case of Pt/SrTiO3 /Pt, but are relatively unaffected in Pt/BaTiO3 /Pt structures. This is consistent with the recent suggestion that subtle variations in interfacial bonding between the dielectric and electrode are critical in determining the ...

Magnetic “Dead” Layer at a Complex Oxide Interface
Physical Review Letters, 2008Recent magnetic measurements at La0.67Ca0.33MnO3/YBa2Cu3O7 interfaces led to conflicting interpretations: a magnetic "dead" layer on the LCMO side or antiparallel Cu and Mn magnetic moments. Here we report results of first-principles density-functional calculations of position-dependent magnetic couplings between interlayer and intralayer Mn atoms. The

Magnetic dead layers in sputtered Co40Fe40B20 films
Journal of Applied Physics, 2008The magnetic moment of Co40Fe40B20 electrodes has been investigated as a function of thickness for films prepared by magnetron sputtering on Si∕SiO2∕MgO and Si∕SiO2 substrates. On MgO, the metal film becomes discontinuous and superparamagnetic with no stable ferromagnetic moment below 1.0nm, whereas on Si∕SiO2, there appears to be a 0.7nm dead region ...

Total efficiency of GE detectors—dead layer signal effect
Applied Radiation and Isotopes, 2010Two types of detectors (GC 4018 and BE 5030) were compared regarding the signal from the outer dead layer of the detector. Gamma-spectra of Am-241 were acquired with various delays against the starting signal from an alpha LS probe. Coincidence spectra from both detectors were different.

Origin of the dielectric dead layer in nanoscale capacitors
Nature, 2006Capacitors are a mainstay of electronic integrated circuits and devices, where they perform essential functions such as storing electrical charge, and blocking direct current while allowing alternating currents to propagate. Because they are often the largest components in circuits, extensive efforts are directed at reducing their size through the use ...

Barium ferrite thin films without a dead layer
IEEE Transactions on Magnetics, 1998A barium ferrite layer with low-Ba content was used as an underlayer for a high-Ba content barium ferrite thin film. During the post-deposition annealing, the underlayer which has a lower nucleation rate than the top layer prevented grains from nucleating in the interdiffused region at the interface with the substrate.

On magnetically dead layers at Nb–Co interface
Solid State Communications, 2002Abstract Recent experiments indicate the presence of magnetically dead NbCo alloy layers at the Nb–Co interface. By using the tight-binding linear muffin-tin orbital method in the atomic-sphere approximation, we consider a number of one- and two-layer Nb–Co interfaces formed by disordered or ordered NbCo alloys.

Dead layer effect in silicon detectors: energy deposited
Surface and Interface Analysis, 2010Abstract In the kiloelectronvolt (keV) and sub‐keV electron energy range, the knowledge of the exact energy deposited of electrons on solid state detectors with a dead layer depends strongly on the fraction of electrons backscattered and implanted.

Magnetic dead layer in amorphous CoFeB layers with various top and bottom structures
Journal of Applied Physics, 2010The magnetic dead layer (MDL) in amorphous CoFeB layers is investigated for four different unit structures. These structures are relevant to the synthetic ferrimagnetic (SyF) free layer structure in magnetic tunnel junctions used for high density magnetic random access memory (MRAM). The MDL results for these unit structures are then converted to those

Determination of gold-layer and dead-layer thicknesses for a Si(Li) detector
Nuclear Instruments and Methods, 1973Abstract Proton-induced C(K α ) and O(K α ) X-rays have been used to determine the efficiencies for detection of these X-rays by a Si(Li) detector. The efficiencies permitted evaluation of the effective gold-layer and dead-layer thicknesses for the detector.
