Chemical Elements - Gallium
Pure gallium already melts at 30 C (86 F). It is relatively safe to handle, but eye contact and longer skin contact should be avoided. Solid gallium, fresh and after some time (2 months) at room temperature. The gallium spiral melted a bit and merged with another piece, which was stored in the same box.

Electrochemical co-deposition of gallium and antimonide
Jan 01, 2019 Cyclic voltammetry reveals that the cathodic deposition of gallium occurs at a potential far more negative than the deposition of antimony. Therefore, the concentration of Ga(III) must be higher than the concentration of Sb(III) in the electrolyte bath in order to obtain the GaSb film with Ga:Sb atom ratio of 1:1 via electrodeposition.

On the bulk -Ga2O3 single crystals grown by the
Oct 15, 2014 Doping with Sn increases the free electron concentration in the crystals to high values (~10 19 cm −3) that lead to an immediate spiral formation, while doping with Mg ( 6 wt ppm) provides insulating crystals with reduced probability of the spiral formation. The estimated Mg equilibrium segregation coefficient across the liquid–solid ...
