From quantum phenomenon to macroscopic device, electronic transport in inter-...
Quantum cascade detectors are semi-conductor devices where infrared photons are absorbed in nanometric quantum wells on a picosecond timescale. These high performance... -
Growth mechanism and crystalline defects in ZnO nanowire structures for LEDs
Quantum well ZnO nanowires and p-type doping by nitrogen ion implantation are studied to make ultraviolet light-emitting diodes. O-polar pyramids and Zn-polar... -
Surface wave optics : super-resolution and wave-matter interaction
Interfaces between materials having opposite dielectric constants support electromagnetic waves confined close to these interfaces called surface waves. For metals and... -
Structural, optical and electronic properties of InN films and In rich hetero...
The nitride semiconductors (AlN, GaN, InN) are subject to a large research effort due to their numerous applications, such as light emitting diodes, high power and... -
Sb surfactant mediated growth of InAs/AlAsSb quantum wells up to 8 monolayers
We study the effect of Sb mediated growth on InAs layers on AlAsSb on InP substrate. The structural and optical characterisations show that InAs QW of at least 8ML can... -
Generation and amplification of surface plasmon polaritons at telecom waveleng...
The field of plasmonics is experiencing a rapid development, due to the interest in studying the behavior of light at the nanometer scale. Key ingredients of plasmonics... -
