Hot wire chemical vapour deposition (HWCVD) of boron carbide thin films from ortho-carborane for neutron detection application

Detection of neutrons is possible if suitable converters such as Li, LiF or ¹⁰B in the form of thin films are used along with the semiconductor device. The use of boron (¹⁰B) in some host matrix as a neutron detector is attractive due to its large neutron capture cross-section. Boron carbide (BC) films are deposited on silicon substrates by HWCVD technique using solid ortho-carborane (o-C₂B₁₀H₁₂) precursor with argon as carrier gas. The films contain ¹⁰B required for neutron detection as confirmed by the Secondary Ion Mass Spectroscopy. Variations in its structure as well as the chemical bonding configurations using Fourier Transform Infra-Red, Raman and X-ray diffraction spectroscopy have been studied.     

Experimentation with hypercube database engines

Using Intel's iPSC/2 hypercube, the authors measured the relationship between packet size, method of clustering messages, and internode traffic on the total sustained communication bandwidth. Having measured the costs associated with internode communication, they then analyzed duplicate removal algorithms. They also studied the effects of nonuniformly distributed attribute values and tuples across processors on three proposed duplicate removal algorithms. They chose algorithms to represent the several available in the literature and then evaluated the output collection time. The authors present a brief overview of the iPSC/2's hypercube message-passing system and discuss the results of their experimentation and analysis
