A light-trapping-structure vertical Ge photodetector(PD)is demonstrated.In the scheme,a 3μm radius Ge mesa is fabricated to constrain the optical signal in the circular absorption area.Benefiting from the light-trapp...
A CR-structure on a 2n +1-manifold gives a conformal class of Lorentz metrics on the Fefferman S1-bundle. This analogy is carried out to the quarternionic conformal 3-CR structure (a generalization of quaternionic CR-...

We obtain rigidity results on arbitrary proper holomorphic maps F from an irreducible bounded symmetric domain Ω of rank ≥2 into any complex space Z. After lifting to the normalization of the subvariety F (Ω) Z, we...
After a brief review of the basic notions the paper defines the G^L-structuresand their partial ordering. On this basis, the paper proves the necessary and sufficientconditions for G^L-structures to form bounded latti...
The concepts of logically constrained overall systems and subsystems of recon-structability analysis are introduced. Then the paper gave an important basis for furtherresearches of the author-the sufficient conditions...
