X-ray photoelectron spectroscopy (XPS) is a surface-sensitive quantitative spectroscopic technique that measures the very topmost 50-60 atoms, 0.01 um, 5-10 nm of any surface. It belongs to the family of photoemission spectroscopies in which electron population spectra are obtained by irradiating a material with a beam of X-rays.

2023年7月4日 · It is critical to consider the energy resolution of the primary X-rays while performing XPS analysis. In XPS, an anode coated in Al or Mg is bombarded by electrons at a high voltage of between 10 and 15 kV, which is typically utilized as the source of X-rays.

2019年11月9日 · Case #1: An XPS 9350, which is designed for 45W. If you connect a 30W power source, the system will show 30W since that's all that's being offered. If you connect a 60W power source, it will show 45W because that's the most the system is designed to draw.

We here report a new voltage contrast inspection technique based on X-ray photoelectron spectroscopy (XPS) and an electron beam (XPS/EB-VCI). This technique detects an electrical defect (in particular, an electrically open defect) on a semiconductor wafer while simultaneously analyzing the chemical state of the wafer.

2024年4月25日 · This guide discusses the sample, surface, and instrument variables that affect the production of a uniform, low voltage, negative electrical field which, in turn, influences the peak-shapes of high energy resolution, chemical state XPS spectra.

The XPS Lab is a surface science UHV system, designed for X-ray and VUV photoelectron spectroscopy experiments. Thereby, the surface composition and detailed information about chemical states of virtually every material are accessible.

2022年7月23日 · I've spent far too much time trying to solve the XPS 15 9520's power throttling under combined CPU + GPU loads (specifically, the CPU dropping to <15W and sub-1GHz while gaming), so I've decided to share my solution around to hopefully help other owners out.

2022年5月18日 · X-ray source of XPS. Al or Mg-coated anode is struck by electrons from a high voltage around 10-15 kV, AlKα or MgKα radiation lines are produced at energies of 1486.6 eV and 1256.6 eV respectively.

Our most powerful 13-inch XPS yet. Designed from the ground up to be our highest performing flagship. 13 ever so you can do everything you love to do faster. The simplified interiors wow and the best-in-class panels bring your content to life. 28W.

2023年12月13日 · Using a 65W charger for your Dell XPS 13 carries minimal risks, as long as you ensure that the charger is compatible with your laptop and meets the necessary voltage and amperage requirements. However, using a charger with a significantly higher wattage than recommended may pose a risk of overheating or damaging the laptop’s internal components.
