2019 In-House Research Highlights

What Has Been Achieved:

Identification of a new growth method assisted by substrate defects that allows achieves record orientational uniformity in 2D chalcogenides.

Importance of Achievement:

The consequent suppression of inversion domain boundaries allows the synthesis of near-single-crystalline domains with improved transport properties.

Unique Features of the MIP That Enabled Project:

The 2DCC-MIP mission advancing synthesis techniques combining state-of-the-art growth, characterization, and theory efforts.
