Ga1-xMnxSb grown on GaSb substrate by liquid phase epitaxy

open access: yes, 2004
The Gal(1-x)Mn(x)Sb epilayer was prepared on the n-type GaSb substrate by liquid phase epitaxy. The structure of the Gal(1-x)Mn(x)Sb epilayer was analyzed by double-crystal X-ray diffraction.

The maize Ga1-s allele confers protection against ga1 pollen in popcorn and dent corn

open access: yes, 2022
Because corn pollen can be carried great distances by wind, maintaining genetic purity of corn grain is challenging. The challenge is substantially reduced in popcorn, which carries the Ga1-s allele preventing pollination by ga1 plants, which include the
