Vertical-Cavity In-plane Heterostructures: Physics and Applications

Vertical and in-plane heterostructures from WS2/MoS2 monolayers.

Layer-by-layer stacking or lateral interfacing of atomic monolayers has opened up unprecedented opportunities to engineer two-dimensional heteromaterials. Fabrication of such artificial heterostructures with atomically clean and sharp interfaces, however, is challenging. Here, we report a one-step growth strategy for the creation of high-quality vertically stacked as well as in-plane interconne...

Lateral oxidation of InAlAs in InP-based heterostructures for long wavelength vertical cavity surface emitting laser applications

We have studied the wet thermal oxidation of In0.52Al0.48As and its potential application in current and optical confinement in vertical cavity surface emitting lasers VCSELs . Two types of InP-based heterostructures were used to study the effect of adjacent layer compositions on the lateral oxidation behavior of the InAlAs. It was found that the oxidation of In0.52Al0.48As with InP adjacent la...

Photo-thermionic effect in vertical graphene heterostructures

Finding alternative optoelectronic mechanisms that overcome the limitations of conventional semiconductor devices is paramount for detecting and harvesting low-energy photons. A highly promising approach is to drive a current from the thermal energy added to the free-electron bath as a result of light absorption. Successful implementation of this strategy requires a broadband absorber where car...
