The heat flow is then calculated from workpiece dimensions, temperature rise and material properties [5].
The 3D heat transfer analysis used 4 node linear tetrahedron elements along with material data for 42CrMo4 (AISI 4140) specified as thermal conductivity l = 45.1 W/m/K, heat capacity cp = 461 J/kg/K and density r = 7830 kg/m³ [9].
This explains the observation that the increase of heat input is very moderate in comparison to the increase of material removed per time unit (Fig. 6).

Both structures are made of electrically conductive materials, and are separated by a dielectric medium (see Fig. 1).
The electric field and charge dominate neglecting the magnetic effects at higher frequencies, and the polarization effects become important in materials with slight conductivity.

Introduction There is currently a revival of germanium as a substrate material for the development of microelectronic technologies [1]-[5].
As an example, Fig. 1 shows the calculated diffusion current density (Jdiff=qni2D 0.5 /τ0.5 NA) at room temperature versus the substrate doping density (NA), for a Ge n+ -p junction, assuming a recombination lifetime τ of 100 µs in the bulk of the material.
