Application of Maximum Entropy Method to Semiconductor Engineering
The maximum entropy method (MEM) is widely used in research fields such as linguistics, meteorology, physics, and chemistry. Recently, MEM application has become a subject of interest in the semiconductor engineering field, in which devices utilize very thin films composed of many materials. For thin film fabrication, it is essential to thoroughly understand atomic-scale structures, internal fi...
متن کاملImagi,ng of Diffraction Data by the Maximum Entropy Method -anew Approach to Crystallography-
The recent works of the Maximum Entropy Method (MEM) in the field of accurate crystal structure analysis were reviewed, The role of MEM analysis in these works are described by the concept of Imaging of Diffraction Data (IDD). Assuming that the phase problem is solved by direct method or some other way, it is possible to construct the real space image, such as the electron density distribution ...
متن کاملFundamental Study on Neutron Spectrum Unfolding using Maximum Entropy and Maximum Likelihood Method
We present a novel spectrum unfolding code, Maximum Entropy and Maximum Likelihood Unfolding Code (MEALU), based on the maximum likelihood combined with the maximum entropy method, which can determine a neutron spectrum without requiring an initial guess spectrum. We present the basic theory, limitations and assumptions built into the implementation. The performance is checked through an analys...
متن کاملApplication of the maximum entropy method in texture analysis
The problem of estimating the crystallite orientation distribution function (codf) based on the leading texture coefficients is considered. Problems of such a type are called moment problems, which are well known in statistical mechanics and other areas of science. It is shown how the maximum entropy method can be applied to estimate the codf. Special emphasis is given to a coordinate-free form...
متن کاملProtein structures by spallation neutron crystallography
The Protein Crystallography Station at Los Alamos Neutron Science Center is a high-performance beamline that forms the core of a capability for neutron macromolecular structure and function determination. This capability also includes the Macromolecular Neutron Crystallography (MNC) consortium between Los Alamos (LANL) and Lawrence Berkeley National Laboratories for developing computational too...
