Investigation of Internal Pressure and Stress in the Buckled H-implanted Ge Layer

Abstract: Ge samples were implanted at RT and 300 °C by 100 keV H+ ions for a fluence of 1 × 1017 ions/cm2. The surface buckling was observed after post-implantation annealing in the samples implanted at RT. However, for the implantation at 300 °C, surface exfoliation occurred in the as-implanted state. Stylus profilometry revealed that in the case of samples implanted at RT, lateral size of the blisters varied between 3––20 μm, with maximum vertical deflection of the blisters in the range of about 8–55 nm. The lateral size and maximum vertical deflection of the blisters were measured to be about 3–30 μm and 50–210 nm, respectively, for the implantation at 300 °C. AFM showed thickness of the buckled layer to be about 856 and 890 nm for the implantation at RT and 300 °C, respectively. The internal pressure and stress in the buckled layer have been investigated using Foppl-von Karman theory (FvK) of thin plates.

Breakage prevention device for blister packs

Abstract: The present invention is a protective system for a plurality of pills contained within a blisterpack. It includes a plurality of hollow modules formed of a non-flexible plastic material, each hollow module having a sufficient size and shape to fit over individual blister-contained pills in the blister pack, and a plurality of spacing bars connecting the plurality of modular hollow modules. The hollow modules may be arranged in predetermined geometric patterns linearly or in an x-axis, y-axis plane to coincide with the pattern of blisters of a blisterpack so as to fit over the blisterpack for packaging and shipping to prevent breakage and damage to the blisters and the pills contained therein.
