Long-living carriers in a strong electron-phonon interacting two-dimensional doped semiconductor
(Nature Publishing Group, 2019-07-15)
Carrier doping by the electric field effect has emerged as an ideal route for monitoring many-body physics in two-dimensional materials where the Fermi level is tuned so that the strength of the interactions can also be ...
Strain Relaxation in Cu-Al-Ni Shape Memory Alloys Studied by in Situ Neutron Diffraction Experiments
(American Institute of Physics, 2019-02-28)
In situ neutron diffraction is used to study the strain relaxation on a single crystal and other powdered Cu-Al-Ni shape memory alloys (SMAs) around martensitic transformation temperatures. This work is focused on the ...
Ultrahigh Superelastic Damping at the Nano-Scale: a Robust Phenomenon to Improve Smart MEMS Devices
(Elsevier, 2019-03)
Micro and nano pillars of Copper-based shape memory alloys (SMAs) with feature sizes between about 2 mu m and 250 nm are known to exhibit ultra-high mechanical damping due to the nucleation and motion of stress-induced ...
On a Common Mistake in the Description of the Photoelectric Effect
(AIP, 2019-11-01)
The photoelectric effect is one of the key experiments taught during first- or second-year university and high school modern physics courses. It is usually the first experiment to introduce light quantization and the concept ...
