- 1. Phys. Rev. Lett. 98, 096805 (2007) , “Observation of the Linear Stark Effect in a Single Acceptor in Si”, L. E. Calvet, R. G. Wheeler, and M. A. ReedThe Stark splitting of a single fourfold degenerate impurity located within the built-in potential of a metal-semiconductor contact is investigated using low temperature transport measurements. A model is developed and used to analyze transport as a function of temperature, bias voltage, and... (Read more)
- 2. Appl. Phys. Lett. 89, 112107 (2006) , “Determination of the concentration of recombination centers in thin asymmetrical p-n junctions from capacitance transient spectroscopy”, Juan A. Jiménez Tejada, Pablo Lara Bullejos, Juan A. López Villanueva, Francisco M. Gómez-Campos, Salvador Rodríguez-Bolívar, and M. Jamal DeenRecombination centers in thin asymmetrical p-n junctions were analyzed in the context of capacitance transient experiments. The combined effect of the thin low-doped region of the junction and the nonzero value of the occupation factor of the recombination center in the depletion layer... (Read more)
- 3. Appl. Phys. Lett. 89, 041910 (2006) , “Acceptor segregation and nonlinear current-voltage characteristics in H2-sintered SrTiO3”, Seong-Min Wang and Suk-Joong L. KangThe current-voltage characteristics with acceptor segregation at grain boundaries have been investigated in H2-sintered SrTiO3. Al-added SrTiO3 was sintered in H2 and then annealed in air for selective oxidation of grain boundaries. The samples showed... (Read more)
- 4. Phys. Rev. B 74, 245216 (2006) , “Influence of excited states of a deep substitutional dopant on majority-carrier concentration in semiconductors”, Hideharu MatsuuraThe density (NA) and energy level (EA) of an acceptor in a p-type wide-band-gap semiconductor (e.g., SiC, GaN, and diamond) are determined by a least-squares fit of the charge neutrality equation to the temperature dependence of the hole...

- 5. Phys. Rev. B 65, 85312 (2002) , “Magnetic resonance studies of Mg-doped GaN epitaxial layers grown by organometallic chemical vapor deposition”, E. R. Glaser, W. E. Carlos, G. C. B. Braga, J. A. Freitas Jr, W. J. Moore, B. V. Shanabrook, R.L. Henry, A. E. Wickenden, D. D. Koleske, H.Obloh, P. Kozodoy, S. P. DenBaars, U. K. MishraElectron paramagnetic resonance (EPR) and optically detected magnetic resonance (ODMR) experiments have been performed on a set of GaN epitaxial layers doped with Mg from 2.5?1018 to 5.0?1019 cm-3. The samples were also characterized by secondary-ion-mass... (Read more)
- 6. Appl. Phys. Lett. 46, 882 (1985) , “Atomic deuterium passivation of boron acceptor levels in silicon crystals”, J. C. Mikkelsen, Jr.B-doped Si wafers were subjected to atomic-deuterium (D) plasmas to simulate the reactions of atomic hydrogen with substitutional B acceptor levels. Secondary ion mass spectrometry was used to profile the in- and out-diffusion of D, and spreading resistance was used to measure the distribution of... (Read more)
- 7. J. Appl. Phys. 35, 379-397 (1964) , “Diffusion and Solubility of Copper in Extrinsic and Intrinsic Germanium, Silicon, and Gallium Arsenide”, R. N. Hall and J. H. RacetteThe solubilities of substitutional and interstitial copper (Cus and Cui) have been measured in intrinsic and extrinsic n- and p-type Ge, Si, and GaAs, using Cu64. These measurements show that Cus is a triple acceptor in... (Read more)
