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 September 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 January 2029.

Abstract

This program aims to create semiconductor amplifiers with outstanding noise performance in the microwave spectrum. Researchers from the California Institute of Technology (CalTech) and the University of Nevada-Reno (UNR) will accomplish this goal by leveraging a new nanofabrication method, atomic layer etching, which permits semiconductor device manufacturing with atomic-scale precision. If successful, these new…
