Session Emitters
The degree of polarization (DOP) of luminescence of III-V materials is a sensitive function of the strain in the material. The DOP can be measured with a spatial resolution of roughly 1 μm and an rms noise equivalent to a strain difference of 2H10. The DOP can be measured on cleaved facets, surfaces free of metals, or luminescent layers buried by transparent materials or thin films. Thus maps o...
متن کاملBrownian Brownian Motion – I
A classical model of Brownian motion consists of a heavy molecule submerged into a gas of light atoms in a closed container. In this work we study a 2D version of this model, where the molecule is a heavy disk of mass M ≫ 1 and the gas is represented by just one point particle of mass m = 1, which interacts with the disk and the walls of the container via elastic collisions. Chaotic behavior of...
متن کاملHigh Performance Field Emitters
The field electron emission performance of bulk, 1D, and 2D nanomaterials is here empirically compared in the largest metal-analysis of its type. No clear trends are noted between the turn-on electric field and maximum current density as a function of emitter work function, while a more pronounced correlation with the emitters dimensionality is noted. The turn-on field is found to be twice as l...
متن کاملUnderstanding Lyα emitters
This publication contains the conference summary of the Understanding Lyα Emitters conference held at the Max Planck Institute for Astronomy in Heidelberg October 6 10, 2008. The scope of the conference was to bring together most of the scientists working in the field of Lyα emitters, whether at low or high redshift, or on observational or theoretical aspects, and to summarise how far the field...
متن کاملDosimetry of internal emitters.
Response and toxicity prediction is essential to rational implementation of cancer therapy. The biologic effects of radionuclide therapy are mediated via a well-defined physical quantity, the absorbed dose, which is defined as the energy absorbed per unit mass of tissue. The concepts, basic definitions, and different approaches to the clinical implementation of absorbed dose estimation are revi...
