Kelvin probe force microscopy (KPFM)

The object of the tender process is a Kelvin probe force microscopy (KPFM) equipped with atomic force microscopy (AFM) functionality, a state-of-the-art detector system, and equipment for advanced material surface potential mapping with an efficient spatial resolution and a minimum of topographical artifacts (later also “Equipment”). The equipment should support both AM- and FM-KPFM modes, operate with a potential range up to ±10 V, with a reasonable spatial resolution. The applied voltage should be from a few hundred millivolts to a few volts (approximately 1-2 V) for AC and DC, and the device must be equipped with advanced control electronics and software for quantitative analysis. An integrated cooling and heating control with a large temperature range (from possibly -30°C up to +90°C) in both air and liquid environments is required to enable in-situ studies under variable atmospheric conditions. The system should provide stable scanning, possibly flexible imaging modes of tapping and/or non-contacting, and compatibility with applications across metals and energy materials. Because of this, the system must allow large samples with complex topography. The technical specification of the equipment and the tender process to be supplied is discussed in more detail in the invitation to tender documents. The object of the tender process is described in more detail in the invitation to tender documents.

The objective is to find one professional supplier that can supply high-quality equipment, equipment installation, and user training. VTT Technical Research Centre of Finland Ltd will choose one supplier from among the tenderers.
