Impact of terahertz short pulses on the oxygen defect state in TiO
Paola Di Pietro, Johannes Schmidt, Nidhi Adhlakha +7
Oxygen deficient titanium dioxide (TiO) is a very attractive material for several applications ranging from photocatalysis to resistive switching. Oxygen vacancies turn ins…
Terahertz Saturable Absorption from Relativistic High-Temperature Thermodynamics in Black Phosphorus
Nidhi Adhlakha, Zeinab Ebrahimpour, Paola Di Pietro +7
Thanks to its tunable infrared band-gap and to its anisotropic conduction properties, black phosphorus represents a very unique 2D material, whose potential in the engineering of n…
Non-adiabatic suppression of 3D excitonic screening in black phosphorus by mid-infrared pulses
Angela Montanaro, Francesca Giusti, Matteo Zanfrognini +10
The competition between the electron-hole Coulomb attraction and the three-dimensional dielectric screening dictates the optical properties of layered semiconductors. In low-dimens…
Pressure tuning of light-induced superconductivity in K3C60
A. Cantaluppi, M. Buzzi, G. Jotzu +7
Optical excitation at terahertz frequencies has emerged as an effective means to manipulate complex solids dynamically. In the molecular solid K3C60, coherent excitation of intramo…
Interband characterization and electronic transport control of nanoscaled GeTe/SbTe superlattices
Antonio Caretta, Barbara Casarin, Paola Di Pietro +8
The extraordinary electronic and optical properties of the crystal-to-amorphous transition in phase-change materials led to important developments in memory applications. A promisi…
