This paper proposes a mechanism to exchange dynamic media-based charging information over the Session Initiation Protocol (SIP), and also proposes a means for negotiation between the entities invol

Mechanisms relevant for the COD in GaAs-based diode lasers are reviewed. Experiments, where COD is artificially provoked, represent a main topic.

Because of well-known surface segregation effects in MBE growth, Si dopant atoms deposited as thin layers in Al sub x Ga sub 1-x As typically become distributed over many atomic layers.

Because of well-known surface segregation effects in molecular beam epitaxy growth, Si dopant atoms deposited as thin layers in AlxGa1-xAs typically become distributed over many atomic layers.

We have studied the process of buried oxide formation as a function of implantation and annealing conditions.

Dendritic spines receive most excitatory inputs in the vertebrate brain, but their function is still poorly understood.

The physical mechanisms underlying RF current-collapse effects in AlGaN-GaN high-electron-mobility transistors are investigated by means of measurements and numerical device simulations.
