Photocatalytic reduction of CO2 provides an opportunity to reach carbon neutrality, by which CO2 emissions from fuel consumption can be converted back to fuels. The challenge is to explore materials ...

Four models of current spreading in double-heterostructure stripe-geometry lasers, both with and without a zinc diffused cap, are presented and compared. These models range in complexity from a simple ...

Planar heterostructures composed of two or more adjacent structures with different materials are a kind of building blocks for various applications in surface plasmon resonance sensors, rectifiers, ...
