Abstract:We have investigated the chemical interaction between a Au/V/Al/V layer structure and n-type AlN epilayers using soft x-ray photoemission, x-ray emission spectroscopy, and atomic force microscopy. To understand the complex processes involved in this multi-component system, we have studied the interface before and after a rapid thermal annealing step. We find the formation of a number of chemical phases at the interface, including VN, metallic vanadium, aluminum oxide, and metallic gold. An interaction mechanism for metal contact formation on the entire n-(Al,Ga)N system is proposed.

“…3a. SALSA includes a custom-built analysis (vacuum) chamber (with the attached flow-through liquid cell), a high-resolution high-transmission x-ray spectrometer described in more detail below and in [17], and a Specs PHOIBOS 150MCD electron analyzer. For solid sample measurements the cell can be replaced by a custom-built preparation chamber with a standard UHV manipulator and surface preparation equipment, as discussed below (Fig.…”

“…The new cell is part of a synchrotron endstation dedicated to the study of liquids and solids, which includes a custom-designed analysis chamber and a high-resolution high-transmission soft x-ray spectrometer [17] in addition to a state-of-the-art electron spectrometer. After describing the liquid cell design in Section 2, this endstation will be described in Section 3 of this paper.…”

Abstract:We present a novel synchrotron endstation with a flow-through liquid cell designed to study the electronic structure of liquids using soft x-ray spectroscopies. In this cell, the liquid under study is separated from the vacuum by a thin window membrane, such that the sample liquid can be investigated at ambient pressure. The temperature of the probing volume can be varied in a broad range and with a fast temperature response. The optimized design of the cell significantly reduces the amount of required sample liquid and allows the use of different window membrane types necessary to cover a broad energy range. The liquid cell is integrated into the SALSA (Solid And Liquid Spectroscopic Analysis) endstation that includes a high-resolution, high-transmission x-ray spectrometer and a state-of-the-art 2 electron analyzer. The modular design of SALSA also allows the measurement of solid-state samples. The capabilities of the liquid cell and the x-ray spectrometer are demonstrated using a RIXS (resonant inelastic x-ray scattering) map of a 25 wt% NaOD solution.

“…[5][6][7][8][9][10][11][12][13] In recent years, new high resolution soft X-ray spectrometers based on varied line spacing gratings have been build. [20][21][22][23][24][25] Some are even able to resolve vibrational states in the spectrum. 26 Yet, they are huge setups with detector arm length of up to 5 m. 22 Future spectrometer projects are even planned with detector arm length up to 15 m with the aim to reach higher resolving power.…”

(Received XXXXX; accepted XXXXX; published online XXXXX) (Dates appearing here are provided by the Editorial Office)We present a newly designed compact grating spectrometer for the energy range from 210 eV to 1250 eV, which would include the Kα 1,2 emission lines of vital elements like C, N and O. The spectrometer is based on a grazing incidence spherical varied line spacing (VLS) grating with 2400 l/mm at its center and a radius of curvature of 58542 mm. First results show a resolving power of around 1000 at an energy of 550 eV and a working spectrometer for high vacuum (10 -4 mbar) environment without losing photon intensity.
