Superconductivity modulated by quantum size effects.
We have fabricated ultrathin lead films on silicon substrates with atomic-scale control of the thickness over a macroscopic area. We observed oscillatory behavior of the superconducting transition temperature when the film thickness was increased by one atomic layer at a time. This oscillating behavior was shown to be a manifestation of the Fabry-Perot interference modes of electron de Broglie ...
متن کاملlanguage learning strategies and vocabulary size of iranian efl learners
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
Study of quantum size effects and optical characteristics in colloidal Cd1-xSnxTe quantum dotes
In this work, we report, optical properties of Cd1-xSnxTe quantum dots (x= 0.05, 0.10 and 0.15) synthesized in water using thioglycolic acid (TGA) as a modifier agent. The optical characterization of the samples was performed through absorption (UV) and photoluminescence spectra (PL). A red shift absorption and fluorescent emission peaks was observed which can be related t...

متن کاملCriticality and Decision Tree Size of AC
We show that the decision tree size of a function f : {0, 1} → {0, 1} computed by an AC circuit of depth d and size s is at most O(2(1−p)n) where p = 1/O(log s)d−1. This result follows from an exponential tail bound on the decision tree depth of the randomly restricted function f Rp: for all t ≥ 0, we show that P[ DTdepth(f Rp) ≥ t ] ≤ exp(−t). For t ≤ log s, this is a straightforward consequen...
