Cornell researchers have developed a new method to create a thin film of semiconductor material that could lead to more efficient photovoltaic cells and batteries.  The "holy grail" for such applications has been to create a thin film of single crystals--with a 3-D structure at the nanoscale--on top of a silicon base.  The tricky part is getting the crystal lattice of the film aligned in the same direction (epitaxially) as in the silicon base.

The U.S. National Science Foundation propels the nation forward by advancing fundamental research in all fields of science and engineering. NSF supports research and people by providing facilities, instruments and funding to support their ingenuity and sustain the U.S. as a global leader in research and innovation. With a fiscal year 2023 budget of $9.5 billion, NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and institutions. Each year, NSF receives more than 40,000 competitive proposals and makes about 11,000 new awards. Those awards include support for cooperative research with industry, Arctic and Antarctic research and operations, and U.S. participation in international scientific efforts.
