We discuss the design and performance of TEXES, the Texas Echelon Cross Echelle Spectrograph. TEXES is a mid-infrared (5-25 µm) spectrograph with several operating modes: high-resolution, cross-dispersed with a resolving power of R = λ/δλ ≈ 100,000, 0.5% spectral coverage, and a ∼ 1.5 × 8 ′′ slit; medium-resolution long-slit, with R ≈ 15,000, 0.5% coverage,(More)
The structural and physical properties of conducting amorphous Zn-doped SnO 2 (a-ZTO) films, prepared by pulsed laser deposition, were investigated as functions of oxygen deposition pressure (pO 2), composition, and thermal annealing. X-ray scattering and X-ray absorption spectroscopy measurements reveal that at higher pO 2 , the a-ZTO films are highly(More)
The structural, electronic and magnetic properties of Cun+1 and CunV (n = 1-12) clusters have been investigated by using density functional theory. The growth behaviors reveal that V atom in low-energy CunV isomer favors the most highly coordinated position and changes the geometry of the three-dimensional host clusters. The vibrational spectra are(More)
We present arcsecond-scale mid-ir photometry (in the 10.5 µm N band and at 24.8 µm), and low resolution spectra in the N band (R ≃ 100) of a candidate high mass protostellar object (HMPO) in IRAS 18151-1208 and of two HMPO candidates in IRAS 20343+4129, IRS 1 and IRS 3. In addition we present high – 2 – resolution mid-ir spectra (R ≃ 80000) of the two HMPO(More)
