Surface Passivation of GaAs Nanowires Ensembles for Photovoltaic Applications

Chia A.C.E., LaPierre R.R., McMaster University, CA

Fabrication, electrical characterization and analytical modeling of an AlInP-passivated GaAs NW ensemble is presented. Novel processing steps were used to fabricate NW ensemble devices which were subsequently characterized electrically and fit with an analytical model, [...]

A Physics-Based Empirical Model for Ge Self Diffusion in Silicon Germanium Alloys

Rabie M.A., Haddara Y.M., McMaster University, CA

We propose a physics-based model for the Ge diffusivity in SiGe and empirically fit the model to previously reported experimental results. The self-diffusivity of Ge can be given by: DGe=D0*exp(Sx)*exp(-E/kT) where x is the Ge [...]

Effect of Strain on the Oxidation Rate of Silicon Germanium Alloys

Rabie M.A., Gou S., Haddara Y.M., Knights A.P., Wojcik J., Mascher P., McMaster University, CA

We report on a series of experiments in which a strained Si0.95Ge0.05 layer 600Å thick was oxidized along with relaxed SiGe layers and Si samples. In this work, we observed that the oxidation rate of [...]

Modeling Germanium-Silicon Interdiffusion in Silicon Germanium/Silicon Super Lattice Structures

Hasanuzzaman M., Haddara Y.M., Knights A.P., McMaster University, CA

Intermixing at heterointerfaces and the broadening of the SiGe layer in SiGe/Si super-lattice (SL) structures can be detrimental to device performance. Thus it is important to develop predictive model for interdiffusion in SL structures. In [...]

Modeling Voids in Silicon

Hasanuzzaman M., Haddara Y.M., Knights A.P., McMaster University, CA

Voids in silicon are used for gettering transition metals and may be used to detect point defect injection. High energy implants can create a separation between vacancies and interstitials making a vacancy rich region near [...]

Modeling the electrical characteristics of FET-type sensors for biomedical applications

Deen M.J., Shinwari M.W., McMaster University, CA

Uniquely examining and identifying biological pathogens is of great importance in health care, as it facilitates early detection, isolation and possibly prevention of many diseases. Availability of highly efficient and easily produced sensors could have [...]
