In the new polymer systems, the required cavities are formed by means of e . g . stamps, templates, laser cutting, etc . Thermo-forming of layer systems from electret films led to thermally more stable ferroelectrets.

The method works on a layer-by-layer system, first solving a cross typically on the bottom, continuing to solve the first two layers ( F2L ), orienting the last layer ( OLL ), and finally permuting the last layer ( PLL ).

They also demonstrated sub-surface measurements looking through a 50 ?m undoped YSZ layer and detecting the phosphorescence of a thin ( 10 �m ) YSZ : Eu layer ( bi-layer system ) underneath using the ESAVD technique to produce the coating.

He was awarded more than two million ?mainly from the Federal Ministries BMU and BMBF, to a minor degree also by the Solar Energy Division at HMI to build and equip laboratories for the development of vacuum preparation techniques for ultra-thin organic layer systems.

Services from the FBH comprise e . g . prototyping of electronical and optoelectronical GaAs devices, epitaxy of GaAs-based layer systems, the development of GaAs processes, pilot series of integrated microwave circuits and laser diodes, consulting in rf measurement technology and the simulation of coplanar waveguide circuits.

The process of calculating the elastic moduli of individual layers in a multi-layer system ( e . g . asphalt concrete on top of a base course on top of the subgrade ) based on surface deflections is known as " backcalculation ", as there is no closed-form solution.
