We report on the liquid-phase epitaxial (LPE) growth of low doped n-GaSb for long wavelength photodiodes. Very low net donor concentration epilayers (

/cm
3) were grown both from undoped Ga rich solutions in the

C range and by compensation using Ga-rich solutions at

C with intentionally added Te. The preparation of Au-GaSb Schottky diodes for

profiling is also discussed.
