Hall effect in the superconducting and normal states in detwinned and twinned single crystals of zinc-doped yttrium barium copper oxide

Schegolev, Anton IgorevichUniversity of Illinois at Urbana-Champaign2011

We have investigated the influence of zinc doping on the Hall effect in detwinned and twinned single crystals of $\rm YBa\sb2Cu\sb3O\sb{7-\delta}$. We observed the sign reversal of the Hall effect for crystals with superconducting transition temperature (T$\rm\sb{c}$) as low as 58.51K. Below the …

Channeling studies of the location of zinc in gallium-arsenide

Christenson, Kurt KarlUniversity of Illinois at Urbana-Champaign2011

The diffusion of zinc in GaAs is highly anomalous in that the diffusion coefficient (D) is proportional to the zinc concentration squared in marked contrast to Fick's law which predicts that D is concentration independent. D is also very sensitive to the ambient conditions during diffusion, …

III-V OMVPE growth and characterisation of graded AlₓGaₓ₋₁As-GaAs layers and heterointerfaces for the development of GRIN-SCH lasers and Gunn diodes

Thavar, RajanDepartment of Chemical Engineering1994

… with controllable silicon, tellurium and zinc doping on both material systems. The OMVPE system is sufficiently calibrated to grow sharp transitions in GaAs doping interfaces and quantum wells in the order of 2.5 nm. SIMS measurements showed almost square doping profiles in the 35 GHz Gunn …

Hall effect in the superconducting and normal states in detwinned and twinned single crystals of zinc-doped YBa2Cu3O7-d

Schegolev, Anton Igorevich2011

We have investigated the influence of zinc doping on the Hall effect in detwinned and twinned single crystals of YBa2Cu307..o. We observed the sign reversal of the Hall effect for crystals with superconducting transition temperature (Tc) as low as 58.51 K. Below the transition temperature, the Hall …
