Thermal Properties of subsurface layer

by At Pampa La Bola, Seiichi Sakamoto, Hideharu Ishizaki
"... We monitored subsurface temperature for more than 2 years at Pampa La Bola every 20 cm down to 100 cm, and evaluated hourly temperature change, apparent thermal diffusiv-ity, freezing points, and maximum depth to frost line. Hourly temperature changes at 0–40 cm is dominated by diurnal cycle, wherea ..."

C 2011 American Chemical Society Influence of Subsurface Layers on the Adsorption of Large OrganicMolecules on Close-Packed Metal Surfaces

by Robin Ohmann, Giacomo Levita, Lucia Vitali, Ro De Vita, Klaus Kern , 2011
"... The adsorption behavior of moleculesand adatoms on surfaces is governedby adsorbate-substrate interactions, such as physisorption and chemisorption. Provided the adsorbates have sufficient energy to overcome the migration barriers, the preferred adsorption sites are those of minimumenergy. Besides t ..."

the chemical nature and positions of atoms in the upper layer, the potential landscape on surfaces is deter-mined also by the atomic arrangement of subsurface layers. On close-packed surfaces, such as Cu(111), the hollow-sites of the first layer are not equivalent, but can be distin-guished between so

Reflection from Layered Surfaces due to Subsurface Scattering

by Pat Hanrahan, Wolfgang Krueger , 1993
"... The reflection of light from most materials consists of two major terms: the specular and the diffuse. Specular reflection may be modeled from first principles by considering a rough surface consisting of perfect reflectors, or micro-facets. Diffuse reflection is generally considered to result from ..."

multiple scattering either from a rough surface or from within a layer near the surface. Accounting for diffuse reflection by Lambert's Cosine Law, as is universally done in computer graphics, is not a physical theory based on first principles. This paper presents

Subsurface microscopy of interconnect layers of an integrated circuit

by F. Hakan Köklü, M. Selim Ünlü , 2009
"... We apply the NA-increasing lens technique to confocal and wide-field backside microscopy of integrated circuits. We demonstrate 325 nm � � 0/4 � lateral spatial resolution while imaging metal structures located inside the interconnect layer of an integrated circuit. Vectorial field calculations are ..."

Physical Reproduction of Materials with Specified Subsurface Scattering

by Martin Fuchs, Wojciech Matusik, Hanspeter Pfister, Szymon Rusinkiewicz
"... Figure 1: Left: photographs of slabs fabricated using a multi-material 3D printer. We use a goal-driven optimization approach to find a volumetric arrangement of base material layers that best approximates an input heterogeneous subsurface scattering function. Right: the layering can also be applied ..."
