Donor behavior in indium-alloyed silicon [PDF]

open access: yes, 1970
The anomalous doping behavior of Si regrown from In solution was studied by (1) Schottky barrier evaluation of conductivity type, (2) electron microprobe analysis for phosphorus, and (3) channeling effect measurements for interstitial In.

The effect of phosphorus on the iron redox ratio, viscosity, and density of an evolved ferro-basalt [PDF]

open access: yes, 1994
Despite the abundant evidence for the enrichment of phosphorus during the petrogenesis of natural ferro-basalts, the effect of phosphorus on the physical properties of these melts is poorly understood.

Single‐cell/nanoparticle trajectories reveal two‐tier Lévy‐like interactions across bacterial swarms

open access: yesView, 2022
Swarming bacteria can organize themselves into different local communities, ranging from active cell rafts to reticular biofilms. How millions of motile and immotile cells are dynamically linked together and still function as a whole is a critical ...
