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

Highly efficient and low-cost light emitting diodes (LEDs) are critical for the future energy landscape in the United States. They are widely used in displays and lighting. Current technologies use high temperature and high vacuum for materials processing and device fabrication, which are energy- and infrastructure-demanding. In this project, LED devices based on a new type of semiconductors—the so-called…
