We supply a hypothesis that explains threshold voltage (Vth) drift under dynamic bipolar gate stress in SiC-MOSFETs, postulating that ionized donor-like interface traps in the lower half of the bandgap, give rise to an increased internal electric fie

Atmospheric gravity waves transport energy and momentum through the atmosphere and can travel large horizontal and vertical distances from the troposphere to the mesosphere and higher. They contribute to atmospheric dynamics and among others drive th

The line emission from the various roto-vibrational bands of the OH radical is an important tracer of the chemistry and dynamics in the Earth's nocturnal mesopause region between about 80 and 100 km. As most studies have focused either on a few brigh

The Atacama Desert in the Chilean Andes region is one of the dryest areas in the world. Due to its unique location with stable subtropical meteorological conditions and high mountains, it is an ideal site for the astronomical telescope facilities of

A low-inductive half-bridge and gate driver package with on-package gate and dc-link capacitors is realized by printed circuit board (PCB) embedding of two GaN-on-Si ICs. While monolithic half-bridge and driver integration reduces on-chip parasitics,

OH airglow is an important nocturnal emission of the Earth's mesopause region. As it is chemiluminescent radiation in a thin medium, the population distribution over the various roto-vibrational OH energy levels of the electronic ground state is not

The nighttime near-infrared radiation of the Earth's atmosphere is mainly produced in the mesopause region between 80 and 100 km by chemiluminescent emission of the OH radical. The line radiation of various vibrational and rotational states is theref

Differential optical absorption spectroscopy (DOAS) has become a standard method for analysing the amount of various molecular species in the Earth's atmosphere. For student education we have developed a small device aiming to be used for practising

The ablation of cosmic dust entering the atmosphere causes the formation of an atomic potassium (K) layer in the mesopause region. It can be studied via resonance fluorescence from the K(D1) line at 769.9 nm, stimulated by sunlight or a laser. In add

Chemiluminescent emission from the mesopause region between 75 and 105 km dominates the Earth's low-to-mid-latitude nocturnal radiation in the wavelength domain from the near-UV to the near-IR. This nightglow consists of various roto-vibrational band
