Smarter, Cheaper Way to Shape Semiconductor Surfaces

July 5, 2025

Researchers have found a new way to shape semiconductor surfaces. They used a simple cracking method on GaAs substrates. This avoids expensive photolithography and etching steps. The method creates tiny, precise V-shaped grooves. The key is a thin layer of nickel. By changing its thickness, they co
