1. A glass substrate, comprising:
a first major surface comprising a periodic first texture, the first texture comprising a first magnitude and a first spatial period in a first direction along a first axis parallel to the first major surface, the first texture extending a length along the first axis equal to or greater than two times the first spatial period, and an isotropic second texture co-located with the first texture, the second texture comprising an average surface roughness Sa equal to or less than 1 nanometer,
wherein the first magnitude is in a range from 2 nanometers to 500 nanometers, and
wherein the first major surface further comprises a periodic third texture co-located with the first texture, the third texture comprising a second magnitude and a second spatial period along a second axis parallel to the first major surface and different from the first axis, the third texture extending a length along the second axis equal to or greater than two times the second spatial period.
