Scamarcio’s scientific excursus is characterized by the proven ability to explore the physical limits of relevant phenomena towards their applications, by contributing to a variety of topics such as: light-matter interaction in layered crystals, semiconductor quantum heterostructures and optoelectronic devices; design and fabrication of quantum cascade lasers and their applications; design and fabrication of thin film transistors for molecular sensing. This evolution stems from a solid background in solid-state physics, spectroscopy and photonics developed in the course of the degree and the PhD courses in physics, under the supervision of Prof. Aldo Cingolani.

His capability of focusing on state-of-the-art physical problems in the exploding field of quantum heterostructures and their peculiar structural and vibrational properties, as  manifested in Raman and infrared spectroscopies, was further refined during a post-doc at the Max-Planck-Institute for Solid State Physics, Stuttgart, one of the leading labs in the field, under the supervision of Prof. Manuel Cardona and Klaus Ploog. During a post-doc stage at the Walter-Schottky-Institute, Munich, on the micro-probe Raman spectroscopy, under the supervision of Prof. Gerhard Abstreiter, posed the bases for the development of an innovative technique for the investigation of optoelectronic devices in-operando, that allowed to experimentally assess fundamental properties and to discover unexpected out-of-equlibrium intersubband electronic and phononic populations in quantum structures and devices.

While already permanent researcher at the University of Bari, he wanted to have a strong international experience at the frontier of quantum device physics and thanks to his strong competences in 1994 he managed to be hired for a 2-years sabbatical at Bell Laboratories of AT&T (later Lucent Technologies), in their world-renowned site of Murray Hill (NJ-USA), in the group of Prof. Federico Capasso. His main achievement was the invention and patenting of the superlattice scheme of quantum cascade lasers, which paved the way to the increase of the emitted power of these unique mid-infrared sources by more than two orders of magnitude, in the Watt-level, which has been a milestone prerequisite for a subsequent plethora of applications. [G. Scamarcio et al., Science 276, 773-776 (1997), US Patent 5,936,989].

Back to Italy, he decided to invest his scientific and technological experience also in favor of the creation and management of a public-private network among universities, public research entities, large and medium enterprises, focusing on research and development or technological transfer in the field of mechatronics, which is the leading industrial sector in the area of Bari. Eventually, this effort leaded to the creation of the technological cluster on mechatronics (MEDIS in 2007. At the same time, he focused his research activity on the study of self-mixing phenomena in semiconductor and quantum cascade lasers for metrological applications and real-time monitoring of laser material processing, quartz-enhanced mid-IR and terahertz photoacoustic sensors, ultra-sensitive chemical sensors based on thin film transistors.

Lately, he engaged in a new challenge by contributing to the creation of a multidisciplinary team developing sensors based on electrolyte-gated organic field effect transistors and studying the collective effects underlying their extreme capability to detect zepto-molar bio-marker concentrations equivalent to single molecule sensing, with mm-sized devices [Nature Communications 9, 3223, (2018), International patent applications PCT/IB2019/061345, PCT/IB2018/050491, PCT/IB2018/053611, PCT/IB2017/058065].
