Cathode related current collapse effect in GaN on Si SBDs (Schottky Barrier Diode) is investigated in this paper. Capacitance and current relaxation measurements on diodes and gated-VDP (Van Der Pauw) are associated with temperature dependent dynamic Ron transients analysis showing that the main part of the current collapse at the cathode comes from a combination of electron trapping in the passivation...
Children with Autism often show difficulties in adapting to change. Previous studies of cortisol, a neurobiologic stress hormone reflecting hypothalamic–pituitary–adrenal (HPA) axis activity, in children with autism have demonstrated variable results. This study measured cortisol levels in children with and without Autism: (1) at rest; (2) in a novel environment; and (3) in response to a blood draw...
