Exoelectron Emission from Ground Aluminium Surface

Soft X-ray Emission Spectra from Aluminium-niobium and Aluminium-palladium Alloys

A1 Lz.3 emission spectra from AI-Nb and Al-Pd alloys have been measured and compared with the A1 K emission spectra from the same alloys. Information regarding the density of states in the vicinity of aluminium ions has been deduced. 1.0 Introduction. Soft X-ray spectrometry is a well established technique for investigating the density of electron states throughout the valence band of metals or...

Thermionic emission from surface-terminated nanocrystalline diamond

Thermionic electron emission forms the basis of both electron sources for a variety of applications and a direct energy conversion process that is compact and scalable. The present study characterizes thermionic emission from boron-doped nanocrystalline diamond films with hydrogen and nitrophenyl surface termination layers. A hemispherical energy analyzer was used to measure electron energy dis...

Terahertz emission from surface-immobilized gold nanospheres.

Electromagnetic wave emission based on optical rectification at terahertz (THz) wavelengths was observed from surface-immobilized gold nanospheres (SIGNs) above a gold surface. Although the excitation wavelength is off-resonant with the localized surface plasmons, the THz emission field was observed to be approximately 4.8 times greater than that from a percolated gold thin film of 10 nm thickn...

A Ground‐based Search for Thermal Emission from the Exoplanet

Eclipsing planetary systems give us an important window on extrasolar planet atmospheres. By measuring the depth of the secondary eclipse, when the planet moves behind the star, we can estimate the strength of the thermal emission from the day side of the planet. Obtaining a ground-based detection of one of these eclipses has proven to be a significant challenge, as time-dependent variations in...
