A method for forming a semiconductor structure includes providing a semiconductor layer, forming nanocrystals over the semiconductor layer, and using a solution comprising pure water, hydrogen peroxide, and ammonium hydroxide to remove at least a portion of the nanocrystals. A ratio by volume of pure water to ammonium hydroxide of the solution may be equivalent to or less than a ratio by volume of 10:1 of pure water to ammonium hydroxide when ammonium hydroxide has a concentration of 29% ammonia by weight. The step of using the solution to remove the at least a portion of the nanocrystals may be performed at a temperature of 50 degrees Celsius or more. |
