Exploring the frontiers of ultra-high freqency acoustic phonons : insights on cutting-edge research
High-frequency acoustic phonons break the paradigm of “bad guys” in solid-state physics, and take the lead in revolutionizing nanotechnology. Nanophononics, a rapidly developing field of nanotechnology, is the study of acoustic phonons – ultrahigh-frequency acoustic vibrations of atoms …

Manipulating hypersound in mesopouros materials
Physicists and chemists use mesoporous materials to confine ultra-high frequency acoustic phonons. The rapidly advancing field of Nanophononics focuses on the study of hypersound, acoustic waves in the gigahertz to terahertz range, at the nanoscale. These high-frequency acoustic …

Ohmic Behavior in Metal Contacts to n/p-Type Transition-Metal Dichalcogenides: Schottky versus Tunneling Barrier Trade-off
High contact resistance (RC) between 3D metallic conductors and single-layer 2D semiconductors poses major challenges toward their integration in nanoscale (opto)electronic devices. While in experiments the large RC values can be partly due to defects, ab initio simulations suggest …

A nanoguitar with adjustable 2D materials
The frequency of a musical instrument, such as a guitar string, is tunable over more than one octave, i.e. a ratio of two between the maximum and minimum frequency. It is defined as f=(k/m)^0.5 where k is the spring …

ERC Consolidator Grants 2022 : Daniel Lanzilloti Kimura, Laureate for the T-RECS project
Acoustic phonons are usually seen as a primary source of unwanted effects in electronics, optoelectronics, and quantum technologies based on solid-state platforms. This project proposes a series of tunable nanodevices where acoustic phonons constitute, instead, a central resource to …
