Probing interlayer van der Waals strengths of two-dimensional surfaces and defects, through STM tip-induced elastic deformations

Autor: N Sarkar, P R Bandaru, R C Dynes

Publikováno v: Nanotechnology. 34:15LT01

A methodology to test the interlayer bonding strength of two-dimensional (2D) surfaces and associated one (1D)- and two (2D)- dimensional surface defects using scanning tunneling microscope tip-induced deformation, is demonstrated. Surface elastic de

LOCALIZATION AND THE METAL–INSULATOR TRANSITION — EXPERIMENTAL OBSERVATIONS

Autor: R. C. Dynes

Publikováno v: International Journal of Modern Physics B. 24:2072-2089

This article describes a series of experiments, mostly performed by the author and his collaborators over a period of 15 years, attempting to understand with the increase of disorder, the evolution from a Fermi liquid, to a state of localized electro

The Hall effect in a-GdxSi1−x at the metal–insulator transition

Autor: Winfried Teizer, R. C. Dynes, Frances Hellman

Publikováno v: Physica E: Low-dimensional Systems and Nanostructures. 18:266-269

We have measured the Hall effect in 3-d amorphous Gd x Si 1− x films in the critical regime of the metal–insulator transition (MIT) at T=400 mK . a-Gd x Si 1− x exhibits a large negative magnetoresistance which is independent of the orientation

Optical properties of the quasi-two-dimensional dichalcogenides 2H-TaSe $ \mathsf {_2}$ and 2H-NbSe $ \mathsf {_2}$

Autor: Helmuth Berger, S. V. Dordevic, L. Forró, R. C. Dynes, Richard Gaal, Dimitri Basov, Barbara Ruzicka, Leonardo Degiorgi, V. Vescoli, Ernst Bucher

Publikováno v: The European Physical Journal B - Condensed Matter. 33:15-23

We present a comprehensive analysis of the optical constants of the two-dimensional dichalco- genide materials 2H-TaSe2 and 2H-NbSe2, in an attempt to address the physics of two-dimensional corre- lated systems. The title compounds were studied over

Granular superconductors and ferromagnets: A proximity-effect-based analogue

Autor: Aviad Frydman, R. C. Dynes

Publikováno v: Philosophical Magazine B. 81:1153-1165

We present a model and a set of measurements which demonstrate an analogy between superconducting and ferromagnetic granular films. For granular films of either Pb or Ni we are able to deposit sequential layers of different material and measure trans

Density of States of AmorphousGdxSi1−xat the Metal-Insulator Transition

Autor: W. Teizer, R. C. Dynes, Frances Hellman

Publikováno v: Physical Review Letters. 85:848-851

We have determined the electronic density of states of amorphous Gd xSi (1-x), N(GdSi)(E), in the vicinity of the metal-insulator transition by measuring the tunneling conductance dI/dV across a Gd xSi (1-x)/oxide/Pb tunnel junction at low T (T appro
