Surface意思

Surface states are electronic states found at the surface of materials. They are formed due to the sharp transition from solid material that ends with a surface and are found only at the atom layers closest to the surface. The termination of a material with a surface leads to a change of the electronic band structure from the bulk material to the vacuum. In the weakened potential at the surface, new electronic states can be formed, so called surface states. The allowed wave numbers for a given potential are found by applying the usual Born—von Karman cyclic boundary conditions. Consequently, if the cyclic boundary conditions are abandoned in the direction normal to the surface the behavior of electrons will deviate from the behavior in the bulk and some modifications of the electronic structure has to be expected. A simplified model of the crystal potential in one dimension can be sketched as shown in Figure 1. The step potential solid line shown in Figure 1 is an oversimplification which is mostly convenient for simple model calculations. At a real surface the potential is influenced by image charges and the formation of surface dipoles and it rather looks as indicated by the dashed line. The first type of solution can be obtained for both metals and semiconductors. In semiconductors though, the associated eigenenergies have to belong to one of the allowed energy bands. The second type of solution exists in forbidden energy gap of semiconductors as well as in local gaps of the projected band structure of metals.

We found that the number of bacteria transferred to either kind of food didn't depend much on how long the food was in contact with the contaminated surface ——whether for a few seconds or for a surface意思 minute, surface意思. Our material contains hundreds of priapulid worms found on closely associated bedding surfaces in mudstone. It seems like a good idea surface意思 the surface but there are sure to be problems, surface意思.

Islands were selected according to their accessibility, their surface area , and particularly their height above the water. Elongation of the microvilli in this case doubles the total egg surface area. The elongation of the mitochondria may provide the cell with an increased surface area for ion exchange and cellular respiration.

The surface of something is the flat top part of it or the outside of it. Ozone forms a protective layer between 12 and 30 miles above the Earth's surface. A work surface is a flat area, for example the top of a table, desk, or kitchen cupboard, on which you can work. Place the fish on a flat surface and sprinkle the flesh with lemon juice and pepper. When you refer to the surface of a situation, you are talking about what can be seen easily rather than what is hidden or not immediately obvious. Social unrest, never far below the surface in Brazil, has erupted over the last few days

North American Use a piece of wax paper larger than the tablets as your work surface. The surface formed mostly in the last billion years, which makes it fresher and more recently active than any rocky planet other than Earth. B2 [ C ] the outer or top part or layer of something:.

Social unrest, never far below the surface in Brazil, has erupted over the last few days The unpredictability of the real world may bring to the surface a troubling software problem. The surface state dispersion can be measured using a scanning tunneling microscope ; in these experiments, periodic modulations in the surface state density, which arise from scattering off of surface impurities or step edges, are measured by an STM tip at a given bias voltage.

Such a state can propagate deep into the bulk, similar to Bloch waves , while retaining an enhanced amplitude close to the surface.
