Low Resistance Ohmic Contact to P-type Monolayer WSe2

Posted by klaurent Berkeley

Kavli Affiliate: Alex Zettl | Summary:Advanced microelectronics in the future may require semiconducting channel materials beyond silicon. Two-dimensional (2D) semiconductors, characterized by their atomically thin thickness, hold immense promise for high-performance electronic devices at the nanometer scale with lower heat dissipation. One challenge for achieving high-performance 2D semiconductor field effect transistors (FET), especially for p-type […]
