Materials Science

NREL provides fundamental and applied materials science discovery and problem-solving for current and next-generation renewable energy and energy-efficient technologies.

Illustration with bottom row showing a ball-and-stick model and top row showing an orange and black band.  In the ball-and-stick model, the yellow balls are sulfur, the light purple balls are tin, and the gray balls are zinc.  The middle section is a dense configuration of zinc sulfide (ZnS) molecules; to the right and left on this band is a more open, regular configuration of tin sulfide (SnS). The top image represents output from atomic force microscopy for the molecular sections. The outer SnS sections exhibit a thinner irregular black band, and the central ZnS section exhibits a dense black band.

State-of-the-art advances in materials science come from a combination of experiments and computations. The image shows modeled electronic density of states (top panel) of the experimentally observed amorphous/crystalline interface (bottom panel). Note the electronic states that appear in the bandgap of the narrow-gap crystalline semiconductors (left and right sides of the image) when it is placed in contact with the wide-bandgap amorphous material (middle of image).
