Gaetano Scamarcio

Short Bio

Gaetano Scamarcio is Director of the Institute of Nanoscience (Cnr Nano) and Full Professor of Experimental Condensed Matter Physics at the University of Bari (currently on leave). His research spans quantum optoelectronics, photonics, and, more recently, emergent collective phenomena in organic bioelectronics. He held full-time research positions at Bell Laboratories (USA) and the Max Planck Institute for Solid State Physics (Germany), and completed visiting appointments at the Walter Schottky Institute (Munich), Bell Labs, and Université Paris Diderot.

Internationally recognised for inventing the superlattice quantum cascade laser, pioneering detectorless THz nanoscopy, and demonstrating that millimetre-scale electronic and optoelectronic devices can detect single molecules, he has published over 300 papers in leading journals such as Science, Advanced Materials, and Nature Communications. He holds several international patents and has coordinated large-scale national and European research consortia.

Research Interests

Gaetano Scamarcio’s research interests lie at the intersection of quantum optoelectronics, terahertz photonics, and organic bioelectronics. His work explores how collective physical phenomena—such as cooperative charge and dipole modulation and metastable transitions—emerge and can be controlled in both inorganic and organic systems.

He has contributed to:

  • the physics and applications of quantum cascade lasers and in-operando device diagnostics,
  • the development of self-mixing based THz nanoscopy for phase-resolved probing of nanostructures,
  • the demonstration of single-molecule sensitivity and zeptomolar detection in millimetre-scale transistor and graphene-based sensors
  • and the investigation of surface charge instabilities in soft, biofunctional materials.

His current research aims to uncover and harness mesoscale cooperative effects for ultra-sensitive detection and unconventional signal processing in organic electronic platforms.
