Backside polishing detector: a new protection against backside attacks
(2015)
Conference report
Open AccessSecure chips are in permanent risk of attacks. Physical attacks usually start removing part of the package and accessing the dice by different means: laser shots, electrical or electromagnetic probes, etc. Doing this ... -

Negative Refraction Index in 3D MAcroporous Silicon Photonic Crystals
(2011)
Conference report
Restricted access - author's decisionPhotonic crystals (PhC) are sturctured materials, which show very attractive propieties, specially their optical behaviour and electromagnetic wave propagation. In this paper, we simulate a three-dimensional Photonic ... -
Selective thermal emitters based on photonic crystals
(Universitat Politècnica de Catalunya, 2014-10-23)
Doctoral thesis
Open AccessUn dels límits fonamentals que afecta l'eficiència de conversió en cèl·lules fotovoltaiques és la distribució espectral de la radiació solar. D'una banda, només els fotons amb energia superior al gap del semiconductor poden ... -
“Silicon millefeuille” : From a silicon wafer to multiple thin crystalline films in a single step
(2013-04-29)
Article
Open AccessDuring the last years, many techniques have been developed to obtain thin crystalline films from commercial silicon ingots. Large market applications are foreseen in the photovoltaic field, where important cost reductions ... -
Single-Step multiple-layers wafer slicing from macroporous silicon
(2013)
Conference report
Open AccessThere is a rising interest, from both photovoltaics and microelectronics industry, in wafer thickness reduction. During the last decade, it has been steadily reduced from 350 µm to 180 µm, but benefits are foreseen for ... -
Thermal emission of macroporous silicon chirped photonic crystals

Three-dimensional metallo-dielectric selective thermal emitters with high-temperature stability for thermophotovoltaic applications
(2015-03-01)
Article
Open AccessSelective thermal emitters concentrate most of their spontaneous emission in a spectral band much narrower than a blackbody. When used in a thermophovoltaic energy conversion system, they become key elements defining both ...
