When studying the solar spectrum, researchers often search for specific emission lines: prominent wavelengths emitted by ions as their electrons transition from higher to lower energy levels.

This luminous object, aka a kilonova, shines this brightly because of the emission of large amounts ... Temperatures this ...

This means that conduction electrons have higher energies inside diamondoids than outside them, which immediately suggests that diamondoids will have excellent electron-emission properties.

the cathode current is assumed to be due to the emission of electrons from a cold cathode by the high field before the cathode (field current). This high field is generated by the space charge of ...

Amplified spontaneous emission is a physical phenomenon that ... by the dense presence of negatively charged particles (i.e., electrons) and positively charged vacancies (i.e., holes).

The emission of radiation can be analysed by an ‘emission spectrum’. The different coloured lines show the frequencies emitted by electrons in atoms.

Much like the traditional scanning electron microscope (SEM), the field emission scanning electron microscope uses electrons to illuminate a sample, instead of visible light as is used in optical ...

Researchers demonstrate a novel way to control the colour of quantum light at room temperature, unlocking new applications in ...

which allows us to control how it interacts with light and electrons. When we combine it with high-efficiency perovskite QDs, we're able to unlock new behaviors in light emission." One of the key ...

Newly published research demonstrates a novel way of generating phonon-polaritons by making electrons collide with crystal lattice structures. The discovery paves the way for cheaper, smaller ...

Vacuum sealed chamber that contains the field emission gun. A pneumatic valve seals the gun chamber in the event of an accidental vacuum vent. This prevents dust and debris from reaching the tip.
