Electrostatic modulation of excitonic fluid in GaN/AlGaN quantum wells by deposition of few-layered graphene and nickel/gold films
R. Aristegui, P. Lefebvre, C. Brimont +9
Excitons hosted by GaN/(Al,Ga)N quantum wells (QWs) are spatially indirect due to the giant built-in electric field that separates electrons and holes along the growth direction. T…
Atomic resolution interface structure and vertical current injection in highly uniform heterojunctions with bulk GaN
F. Giannazzo, S. E. Panasci, E. Schilirò +11
The integration of two-dimensional with recently attracted significant interest for future electronic/optoelectronic applications. However, the reported studies hav…
Current transport in Ni Schottky barrier on GaN epilayer grown on free standing substrates
Giuseppe Greco, Patrick Fiorenza, Emanuela Schilirò +9
In this paper, the Ni Schottky barrier on GaN epilayer grown on free standing substrates has been characterized. First, transmission electrical microscopy (TEM) images and nanoscal…
Electrical control of excitons in GaN/(Al,Ga)N quantum wells
R. Aristegui, F. Chiaruttini, B. Jouault +7
A giant built-in electric field in the growth direction makes excitons in wide GaN/(Al, Ga)N quantum wells spatially indirect even in the absence of any external bias. Significant…
Dipolar excitons offer a rich playground for both design of novel optoelectronic devices and fundamental many-body physics
F. Chiaruttini, T. Guillet, C. Brimont +6
Dipolar excitons offer a rich playground for both design of novel optoelectronic devices and fundamental many-body physics. Wide GaN/(AlGa)N quantum wells host a new and promising…
Highly resistive epitaxial Mg-doped GdN thin films
C. -M. Lee, H. Warring, S. Vézian +7
We report the growth by molecular beam epitaxy of highly resistive GdN, using intentional doping with magnesium. Mg-doped GdN layers with resistivities of 1000 Ω.cm and carrier con…
Tuning the electromagnetic local density of states in graphene-covered systems via strong coupling with graphene plasmons
Riccardo Messina, Jean-Paul Hugonin, Jean-Jacques Greffet +6
It is known that the near-field spectrum of the local density of states of the electromagnetic field above a SiC/air interface displays an intense narrow peak due to the presence o…
The role of magnetic polarons in ferromagnetic GdN
Franck Natali, Ben Ruck, Joe Trodahl +6
We report an interplay between magnetism and charge transport in the ferromagnetic semiconductor GdN, pointing to the formation of magnetic polarons centred on nitrogen vacancies.…
