The amount absorbed is dependent on the material's mass absorption coefficient and tends to decrease for incident photons of greater energy.
22.
CIGS has an exceptionally high absorption coefficient of more than 10 5 / cm for 1.5 eV and higher energy photons.
23.
The effective scattering height depends on the ozone absorption coefficient and on the solar zenith angle, increasing as with each of these.
24.
Because the material has a high absorption coefficient and strongly absorbs sunlight, a much thinner film is required than of other semiconductor materials.
25.
For a given particle and its energy, the absorption cross-section of the target material can be calculated from mass absorption coefficient using:
26.
This necessitates usage of materials with strong absorption coefficients ? ( ? ), high minority carrier lifetimes ? minority, and high mobilities ?
27.
The absorption coefficient versus incident photon energy contains oscillations which are due to the interference of the backscattered Auger electrons with the outward propagating waves.
28.
The closed-cell structure foams have higher dimensional stability, low moisture absorption coefficients, and higher strength compared to open-cell-structured foams.
29.
Since the EAM requires small size and low modulation voltages, possibility of obtaining quantum dots with enhanced electro-absorption coefficients makes them attractive for such application.
30.
Where A = \ sum S \ times \ alpha is the equivalent absorption area involving the surface S of the walls and their absorption coefficient \ alpha.
