Fabrication and Characterization of Thermally Oxidized Tungsten-Based Thin Films for Application in Cold Field Emission Sources

Popis výsledku v původním jazyce

Thermal oxidation is a methodology employed to generate thin oxide coatings on surfaces. Oxide coatings have demonstrated utility across diverse applications, including cold field electron emission sources. In the realm of commercial microscopy applications, tungsten remains a choice for cold field emission purposes [1] [2]. Its desirable attributes can be further enhanced through the deposition of a thin layer. This not only helps emission characteristics but also extends the operational lifespan of the emitter. Tungsten oxide, recognized for its exceptional resistance to corrosive agents and chemical assaults, owes its durability to its stable crystal lattice and the robust chemical bonds formed between tungsten and oxygen atoms. Several techniques have been employed to achieve this objective, each with distinct advantages and drawbacks [1] [2]. For this work, termooxidation emerged as the chosen method due to its capacity for achieving uniform material coverage and its accessibility without the nec
