Plasma (physics) - Wikipedia

Definitions The fourth state of matter. Plasma is called the fourth state of matter after solid, liquid, and gas. It is a state of matter in which an ionized substance becomes highly electrically conductive to the point that long-range electric and magnetic fields dominate its behaviour.

A two-step physical-chemical etching technique to improve ...

The excitation wavelength was 240 nm (i.e., 5.16 eV), and the slit width for both exciting and emission was 10 nm. The laser-induced damage threshold (LIDT) tests were performed on the rear surfaces of un-etched and etched samples using a single-longitudinal mode Nd:YAG laser (THALES LASER, SAGA) operated at 355 nm with a pulse width of 6.4 ns.

Calibration of the mesa etching has shown that sideway etching of 165 nm occurs on average on either side of the mesa, so the actual mesa width is approximately 1.67 μm. Measurements on other samples created by this process have shown that the lateral edge depletion of the 2DEG is between 0.34 and 0.58 μm.
