Thermal Properties, Molecular Structure, and Thin-Film Organic Semiconductor Crystallization
Jordan T. Dull,Yucheng Wang,Holly Johnson,Komron Shayegan,Ellie Shapiro,Rodney D. Priestley,Yves Geerts,Barry P. Rand +7 more
TL;DR: In this article, the crystallinity of a group of organic small molecules is investigated by vapor depositing the materials into thin films followed by a thermal annealing step, and the materials are categorized into th...
Neutralizing the polarization effect of diamond diode detectors using periodic forward bias pulses
Jason Holmes,Maitreya Dutta,Franz A. M. Koeck,Manpuneet Benipal,Raghuraj Hathwar,Jesse Brown,Benjamin Fox,Holly Johnson,Anna Zaniewski,Ricardo Alarcon,Srabanti Chowdhury,Stephen M. Goodnick,Robert J. Nemanich +12 more
TL;DR: In this paper, a new technique for neutralizing the polarization effect of diamond detectors has been demonstrated, which relies on the diamond detector to be configured as a diode, is to periodically pulse the diamond diode with forward bias.

A comprehensive picture of roughness evolution in organic crystalline growth: the role of molecular aspect ratio.
Jordan T. Dull,Xiangyu Chen,Holly Johnson,Maria Clara Otani,Frank Schreiber,Paulette Clancy,Barry P. Rand +6 more
TL;DR: In this article , the surface roughness of organic semiconductors is measured as a function of adlayer film thickness from which the growth exponent (β) is extracted, and it is shown that low-dimensional molecules that have low molecular aspect ratios tend to remain smooth as thickness increases.

Cleaning diamond surfaces via oxygen plasma inhibits the formation of a TiC interface
TL;DR: In this paper , the authors investigated the interface of oxygen-terminated polycrystalline B-doped diamond and titanium via XPS in an effort to determine if oxygen would rearrange away from the diamond surface and TiC would be formed through post-deposition annealing.

Performance of 5- μm PIN diamond diodes as thermal neutron detectors
Jason Holmes,Jesse Brown,Franz A. M. Koeck,Holly Johnson,Manpuneet Benipal,Praneeth Kandlakunta,Anna Zaniewski,Ricardo Alarcon,Raymond Cao,Stephen M. Goodnick,Robert J. Nemanich +10 more
TL;DR: In this paper, a diamond PIN diodes with an approximately 5-μ m thick i-layer and coated with a thin boron nitride (BN) layer have been tested with a thermal neutron beam.
