Electron emission

In physics, electron emission is the ejection of an electron from the surface of matter, or, in beta decay (β− decay), where a beta particle (a fast energetic electron or positron) is emitted from an atomic nucleus transforming the original nuclide to an isobar.

Mid-Infrared Modulation of Quantum Emitters in Hexagonal Boron Nitride

Single-photon emitters (SPEs) are promising building blocks for practical devices in quantum technologies. Traditionally, these systems are excited using off-resonant visible light through their phonon transitions, yet this process remains poorly understood. Here, we explore the interaction of mid-infrared (MIR) excitation with the properties of SPEs in hexagonal boron nitride. Notably, we present a reversible, nondestructive method to enhance emission from blue SPEs using MIR coexcitation. By resonantly dr

Numerical investigation of vacuum surface flashover triggered by inverted potential gradient on solar cells using particle-in-cell method

Spacecraft electrostatic discharge is a type of surface discharge in vacuum which is commonly known as vacuum surface flashover, posing a significant threat to the safe operation of spacecraft solar cells. This numerical study investigates vacuum surface flashover on spacecraft solar cells triggered by an inverted potential gradient (IPG), using particle-in-cell simulations. Incorporating the realistic solar cell structure [room temperature vulcanized (RTV) adhesive, cover glass, and metal interconnector] a

Carrier capture into semiconductor quantum dots via quantum wire barriers: Localization and thermionic emission effects

Elyahou Kapon

Carrier transport and capture paths via barriers of different dimensionality in AlGaAs/GaAs quantum wire (QWR)/quantum dot (QD) heterostructures, grown in inverted pyramids, are studied by photoluminescence (PL) spectroscopy. Evidence for thermally activated diffusion related to potential disorder in the QWR barriers and thermionic emission of carriers from the QD into the QWR barrier is observed in temperature dependent PL spectra. Similar activation energies for the thermionic emission are derived from th

Marcel Drabbels

Dr. Marcel Drabbels studied experimental physics at the University of Nijmegen (the Netherlands) and in 1993 obtained his Ph.D. at that same university. He then moved to the University of California at Santa Barbara where he studied the dynamics of highly vibrationally excited molecules and developed a new detection technique to investigate the photodissociation of molecules. When he returned to the Netherlands in 1996 he joined the FOM Institute for Atomic and Molecular Physics in Amsterdam where he worked on the development of new types of infrared imaging and streak cameras. In 1997 Dr. Drabbels was awarded a fellowship of the Royal Dutch Academy of Sciences and he moved to the Free University of Amsterdam where he studied the collision dynamics of molecules and initiated photodissociation experiments using ultrafast lasers. In October 1998 he was appointed as senior scientist at the EPFL where he studies the spectroscopy and dynamics of nanoscale systems. In March 2021 he was promoted to titular professor.

Thermionic emission

Thermionic emission (also known as thermal electron emission or the Edison effect) is the liberation of electrons from an electrode by virtue of its temperature (releasing of energy supplied by heat). This occurs because the thermal energy given to the charge carrier overcomes the work function of the material. The charge carriers can be electrons or ions, and in older literature are sometimes referred to as thermions. After emission, a charge that is equal in magnitude and opposite in sign to the total charge emitted is initially left behind in the emitting region.
