Mechanisms for Si Dopant Migration in MBE Al sub x Ga sub x-1 As

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.

Mechanisms for Si dopant migration in molecular beam epitaxy AlxGa1-xAs

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.

Mechanisms of buried oxide formation by ion implantation.

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

Mechanisms of calcium influx into hippocampal spines: Heterogeneity among spines, coincidence detection by NMDA receptors, and optical quantal analysis

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

Mechanisms of formation of thin buried oxide layers by ion implantation.

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

Mechanisms of gate lag in GaN/AlGaN/GaN high electron mobility transistors

The presence of electronic traps in GaN-based transistors limits device performance and reliability.

Mechanisms of gate lag in GaN/AlGaN/GaN high electron mobility transistors

The presence of electronic traps in GaN-based transistors limits device performance and reliability.

Mechanisms of RF current collapse in AlGaN-GaN high electron mobility transistors

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.

Mechanisms of Shear Thinning in Dilute Polymer Solutions

The origin of shear thinning in dilute polymer solutions has been attributed to four different molecular mechanisms: hydrodynamic interaction between monomers, finite extensibility of the polymer

Mechanistic Studies of Silicon Oxidation

The microscopic mechanism of formation of ultrathin oxides on Si(100) has been investigated using a combination of infrared spectroscopy and ab initio quantum chemical cluster calculations.
