Journal ArticleDOI
Freezing of anisotropic spin clusters in La 1.98 Sr 0.02 CuO 4
M. Matsuda,Young S. Lee,Martin Greven,Marc Kastner,Robert J. Birgeneau,Kohta Yamada,Yasuo Endoh,Peter Böni,Seunghun Lee,S. Wakimoto,Gen Shirane +10 more
TL;DR: The spin-glass state can be expressed as a random freezing of quasi-three-dimensional spin clusters with anisotropic spin correlations, and the spin structure is closely related to the diagonal stripe structure.
Journal ArticleDOI
Time-of-flight and photoconductivity studies of a-As2Se3 films
TL;DR: In this article, the dispersive transport in a -As 2 Se 3 is due to multiple trapping in an exponential distribution of localized states, and it is shown that the dispersion is not due to contact-induced effects in time-offlight measurements.
Journal ArticleDOI
Evidence for activated conduction in a single electron transistor
N. Y. Morgan,David Abusch-Magder,Marc Kastner,Yasuo Takahashi,Hiroyuki Tamura,Katsumi Murase +5 more
TL;DR: In this article, it was shown that the dominant conductance mechanism in this temperature range is thermal activation over one of the potential barriers that localize electrons in the quantum dot, which cannot be fully explained by the theory of Matveev and Glazman.
Journal ArticleDOI
Excitation-Energy Dependence of Photoluminescence Bandwidth in a - As 2 S 3 : Observation of the Mobility Gap?
G. S. Higashi,Marc Kastner +1 more
TL;DR: In this article, a new optical system incorporating a fast Ge photodiode has made possible the first measurements at short times of the low-energy side of the photoluminescence spectrum of $a$-${\mathrm{As}}_{2}$${\mathm{S}}_{3} ).
Journal ArticleDOI
Magnetic-field dependence of the level spacing of a small electron droplet.
TL;DR: The temperature dependence of conductance resonances is used to measure the evolution with the magnetic field of the average level spacing of a droplet containing 30 electrons created by lateral confinement of a two-dimensional electron gas in GaAs, suggesting that excitations of the spin degrees of freedom are important.
