Effect of Er dopant in GaSb bulk crystals grown by vertical Bridgman technique [PDF]

Journal of Crystal Growth, 1999
The distribution of Er in bulk GaSb ingots grown by vertical Bridgman technique has been investigated for different concentrations. The resistivity, mobility and carrier density were analysed. The formation of Er-Sb compounds and the incorporation of Er at subgrain boundaries has been shown by cathodoluminescence studies.

Growth of Eu doped LiBr/BaBr2 eutectic and its thermal neutron response

Optical Materials: X, 2023
In this study, Eu:6LiBr/BaBr2 with a high Li concentration was developed as a novel neutron scintillator. Here, an Eu-doped BaBr2 phase acted as a scintillator and 6Li-containing LiBr phase acted as a neutron capturer.

Vertical Bridgman growth of sapphire crystals, with thin-neck formation process [PDF]

, 2014
A new technique is proposed in the traditional vertical Bridgman growth of sapphire crystals, in which thin-neck formation follows the initial seeding. Low-angle grain boundaries generated at the periphery of the seeding interface were eliminated at the ...
