OUTPUT POWER ENHANCEMENT OF GAN-BASED FLIP-CHIP LIGHT-EMITTING DIODES VIA CONICAL STRUCTURES GENERATED BY A MONOLAYER OF NANOSPHERES

Output power enhancement of GaN-based flip-chip light-emitting diodes via conical structures generated by a monolayer of nanospheres

This letter describes the output power enhancement of the GaN-based flip-chip light-emitting PRO VISION diodes (FC LED) featuring conical structures fabricated by etching a self-assembled monolayer SiO2 spheres as the hard mask.By roughening the surface of FC LED components, it increases structural size of the components and elevates the light extr

Role of leptin in the pathogenesis of breast cancer

Leptin is a small polypeptide codified by the Obese Gene (OB), deeply related with the body fat mass and energetic balance.Due to its diverse biological effects and downstream signal transducers, multiple classifications have been attributed to leptin, as hormone, cytokine, adypokine, growth factor, and developmental factor, among others.This scena

Alien leaf beetles (Coleoptera, Chrysomelidae) of European Russia and some general tendencies of leaf beetle invasions.

Invasions of leaf beetles can cause tremendous economic consequences because some of these insects become major pests in invaded territories.We present the first inventory of alien Chrysomelidae of European Russia that appeared in the region in the 20th and 21st centuries (9 species) with analysis of the history of their invasions and detailed maps
