Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 30 June 2029.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 October 2029.

Abstract

Non-technical Abstract: When a metal surface is illuminated by a beam of light, it can emit electrons. This is known as the “photoelectric effect,” and is a foundational milestone of quantum physics. The minimum energy of light quanta required to eject an electron is known as the “work function” of the metal surface. A knowledge of this quantity is needed for the design of a multitude of devices, including light…
