      abstract     = {GaAs is broadly used in modern electronics. The application
                      of GaAs-based devices in high power electronics, however, is
                      complicated due to the substantial excess heat generated
                      during device operation. One possibility to dissipate the
                      excess heat is to employ substrates with high thermal
                      conductivity. In this contribution we present the growth of
                      GaAs layers by metalorganic vapor phase epitaxy (MOVPE) on
                      aluminum (111) pseudosubstrates designed for an improved
                      heat management in GaAs electronic circuits. They were
                      prepared by Al evaporation on (100) GaAs substrates and
                      subsequent heat treatment. The GaAs layers are
                      polycrystalline. The roughnesses of the layers were in the
                      range of 13 to 62 nm and the thickness in the range of 600
                      – 2300 nm. The layers exhibit extremely low carrier
                      lifetime due to the growth-induced defects and are suitable
                      for the fabrication of ultrafast metal-semiconductor-metal
                      (MSM) photodetectors (PDs).},
