Dataset and its properties
To benchmark phonon properties we use the dataset developed in the MDR database34. This dataset includes around 10 000 non-magnetic semiconductors, covering a wide range of elements across the periodic table. Moreover,…

Ultrafast all-optical generation of pure spin and valley currents
Pure spin current
We first consider the generation by laser light of a pure spin current in WSe2; to this end we employ a minimal tight-binding model and evolution according to the von Neumann equation of motion we use a decoherence time T226,27,

A 70 MPa silicon resonant pressure microsensor with resonators supported by micro beams based on volume compressed sensing
Structural design and sensing principle
Figure 1a shows the overall structural design of the microsensor, which mainly consists of two parts: a SOI wafer and a silicon wafer as cap. Micro-beam supports and resonators are placed on the device layer…

Strain-tuning for superconductivity in La3Ni2O7 thin films
Epitaxial thin film
We fabricated La3Ni2O7 thin films on three substrates using pulsed-laser deposition (see Methods for details). To tune the strain, we selected SrTiO3 (001) with (aSTO = 3.905 Å), NdGaO3 (001)pc (aNGO = 3.855 Å)…
