Dynamics of symmetric holomorphic maps on projective spaces
We consider complex dynamics of a critically finite holomorphic map from P^k
to P^k, which has symmetries associated with the symmetric group S_{k+2} acting
on P^k, for each k \ge 1. The Fatou set of each map of this family consists of
attractive basins of superattracting points. Each map of this family satisfies
Axiom A.Comment: 12 page
Dynamics of superattracting skew products on the attracting basins: B\"{o}ttcher coordinates and plurisubharmonic functions
We study the dynamics of a superattracting skew product on the attracting
basin. As the first strategy, we find out forward -invariant wedge-shaped
regions in the basin, on some of which is conjugate to monomial maps, and
consider whether the unions of all the preimages of the regions coincide with
the basin. As the second strategy, we show the existence and properties of
several kinds of plurisubharmonic functions of , the main functions of which
are induced from the B\"{o}ttcher coordinates, and investigate the asymptotic
behavior of the functions toward the boundaries of the unions. Consequently, we
obtain a plurisubharmonic function on the complement of specific fibers in the
basin, which is continuous and pluriharmonic on open and dense subsets of the
complement and describes an certain weighted vertical dynamics well.Comment: 45 pages,16 table
Accumulation and depletion layer thicknesses in organic field effect transistors
We present a simple but powerful method to determine the thicknesses of the
accumulation and depletion layers and the distribution curve of injected
carriers in organic field effect transistors. The conductivity of organic
semiconductors in thin film transistors was measured in-situ and continuously
with a bottom contact configuration, as a function of film thickness at various
gate voltages. Using this method, the thicknesses of the accumulation and
depletion layers of pentacene were determined to be 0.9 nm (VG=-15 V) and 5 nm
(VG=15 V).Comment: 3 pages, 4 figures, Jap. J. Appl. Phys. in pres
