(author), Bechstedt, F. (author), Haverkort, J. E.M. (author), Bakkers, E.P.A.M. (author)Direct band gap III-V semiconductors, emitting efficiently in the amber-green region of the visible spectrum, are still missing, causing loss in efficiency in light emitting diodes operating in this region, a phenomenon known as the "green gap". Novel geometries and crystal symmetries however show strong promise in overcoming this limit. Here...journal article 2018

Assali, S. (author), Lähnemann, J. (author), Vu, TTT (author), Jöns, K.D. (author), Gagliano, L (author), Verheijen, M. A. (author), Akopian, N. (author), Bakkers, E.P.A.M. (author), Haverkort, J. E.M. (author)One of the major challenges in the growth of quantum well and quantum dot heterostructures is the realization of atomically sharp interfaces. Nanowires provide a new opportunity to engineer the band structure as they facilitate the controlled switching of the crystal structure between the zinc-blende (ZB) and wurtzite (WZ) phases. Such a...journal article 2017
