The effects of air, oxygen and water exposure on the sub-bandgap absorption, the electronic conductivity and the ambipolar diffusion length in highly crystalline microcrystalline silicon films for photovoltaic applications
Reversible and irreversible changes due to long term air and short term de-ionized water (DIW) or pure oxygen exposure were investigated in about 1 µm thick hydrogenated microcrystalline silicon (µc-Si:H) film...

Conductance fluctuations in a-Si : H: effects of alloying and device structure
We present measurements of conductance noise in undoped a-Si : H and a-SiGe : H thin films in both a transverse and coplanar electrode geometry. For a-Si : H with coplanar electrodes, the noise spectrum is not...

Feasibility of Long-Term Intraventricular Therapy with Mafosfamide (n = 26) and Etoposide (n = 11): Experience in 26 Children With Disseminated Malignant Brain Tumors
Treatment options for leptomeningeal disseminated brain tumors are limited by the lack of effective drugs for intrathecal therapy of non-hematologic malignancies. We report on our experience with an intraventr...
