- 1. Appl. Phys. Lett. 91, 133507 (2007) , “Identification of atomic-scale defect structure involved in the negative bias temperature instability in plasma-nitrided devices”, J. P. Campbell, P. M. Lenahan, A. T. Krishnan, and S. KrishnanWe utilize a very sensitive electron spin resonance technique called spin-dependent tunneling to identify defect centers involved in the negative bias temperature instability in plasma-nitrided p-channel metal-oxide-silicon field-effect transistors. The defect's 29Si hyperfine... (Read more)
- 2. Appl. Phys. Lett. 90, 123502 (2007) , “Observation of negative bias stressing interface trapping centers in metal gate hafnium oxide field effect transistors using spin dependent recombination”,The authors combine metal oxide semiconductor (MOS) gated diode measurements and very sensitive electrically detected electron spin resonance measurements to detect and identify negative bias temperature instability (NBTI) generated defect centers in fully processed HfO2 pMOS field effect...

- 3. Appl. Phys. Lett. 90, 073507 (2007) , “Fermi-level pinning at polycrystalline silicon-HfO2 interface as a source of drain and gate current 1/f noise”, P. Magnone, F. Crupi, L. Pantisano, and C. PaceThe impact of a submonolayer of HfO2 sandwiched between the SiON gate dielectric and the polycrystalline silicon layer on the low frequency noise of a n-channel metal oxide semiconductor field effect transistor is investigated. Fermi-level pinning at polycrystalline... (Read more)
- 4. Appl. Phys. Lett. 90, 042105 (2007) , “Stress induced leakage current mechanism in thin Hf-silicate layers”, A. Paskaleva, M. Lemberger, and A. J. BauerStress induced leakage current (SILC) in thin Hf-silicate layers and the mechanisms of its creation are examined. A very strong polarity and thickness dependence as well as partial recovery of SILC are observed. It is suggested that the trapping in preexisting sites influences SILC by two ways: (1)...

- 5. Appl. Phys. Lett. 90, 032102 (2007) , “Dynamic nuclear polarization induced by hot electrons”, Yosuke Komori and Tohru OkamotoA method for local dynamic nuclear polarization is demonstrated in a GaAs/AlGaAs heterostructure at the Landau level filling factor ν=3. Using a narrow channel sample, where the width varies stepwise along the electron flow, the authors find that electron cooling (heating) causes the polarization... (Read more)
- 6. Appl. Phys. Lett. 90, 023112 (2007) , “Electrically tunable defects in metallic single-walled carbon nanotubes”, Ji-Yong ParkA defect whose electron transmission probability can be controlled by electric field is intentionally created on a metallic single-walled carbon nanotube (SWCNT) with a voltage pulse from a tip of an atomic force microscope (AFM). Localized characteristics of the created defect are elucidated with... (Read more)
- 7. Phys. Rev. Lett. 98, 146403 (2007) , “Evidence for an Oxygen Diffusion Model for the Electric Pulse Induced Resistance Change Effect in Transition-Metal Oxides”, Y. B. Nian, J. Strozier, N. J. Wu, X. Chen, and A. IgnatievElectric-pulse induced resistance hysteresis switching loops for Pr0.7Ca0.3MnO3 perovskite oxide films were found to exhibit an additional sharp “shuttle tail” peak around the negative pulse maximum for films deposited in an oxygen-deficient ambient. The... (Read more)
- 8. Appl. Phys. Lett. 89, 122112 (2006) , “Interface states for HfO2/Si structure observed by x-ray photoelectron spectroscopy measurements under bias”, Osamu Maida, Ken-ichi Fukayama, Masao Takahashi, Hikaru Kobayashi, Young-Bae Kim, Hyun-Chul Kim, and Duck-Kyun ChoiA 1.0 nm silicon nitride (SiN) layer can prevent reaction between HfO2 and Si completely. In this case, the interface state spectra obtained from x-ray photoelectron spectroscopy measurements under bias have two peaks above and below the midgap, attributable to Si dangling bonds...

- 9. Appl. Phys. Lett. 89, 061103 (2006) , “Field induced photoluminescence quenching and enhancement of CdSe nanocrystals embedded in SiO2”, A. W. Achtstein, H. Karl, and B. StritzkerThe authors describe the operation of an electro-optical photoluminescence quenching device based on CdSe nanoclusters formed using sequential ion implantation of Cd+ and Se+ in thermally grown SiO2 on silicon. A sample geometry consisting of a semitransparent gold... (Read more)

ClarkWe report low-frequency charge noise measurement on silicon substrates with different phosphorus doping densities. The measurements are performed with aluminum single electron transistors (SETs) at millikelvin temperatures where the substrates are in the insulating regime. By measuring the SET... (Read more)
