Near to the edges of the film (or isolated feature), the degree of constraint is reduced as there is no material preventing the edges from moving inward on densification. This means that film in this region is able to densify to a relatively high degree. At the edge of the feature, close to the substrate, the film is constrained, and is also not surrounded by as much material from where matter can be redistributed to relieve the stresses generated. In this region, the density of the film is much lower.
In the case of a powder compact, the total surface energy will be related to the total surface area of all the particles. 3 Thick-film powder-based routes 41 (particles joined) or bulk material (particles fully fused), then the energy of the system can be greatly reduced. The initial stage of sintering is often simplified to the case of two touching spherical particles. The chemical potential of a convex surface, such as the surface of the particle, is higher than the chemical potential of a flat surface, which in turn is higher than the chemical potential of a concave surface.
3 Pyroelectric devices Related to piezoelectric devices are pyroelectric devices, which share a common family of materials. This is because the piezoelectric materials used in thick-film devices are actually ferroelectric materials. In addition to being piezoelectric, these ferroelectric materials are pyroelectric. Pyroelectric materials generate an electrical signal when subjected to changes in temperature. 1 Pyroelectric sensors Responding to changes in temperature, pyroelectric materials are used in a range of thermal-sensing devices including intruder alarms, infrared thermal imagers, and gas sensors.
