2D-schematic illustrating the geometry of a cluster when formed on a seed particle with radius rp.
The newly formed cluster contains n*molecules and is characterized by the corresponding radius of curvature r* from the Kelvin relation (see main text for detailed explanations). Interaction between cluster and particle surface leads to corresponding contact angle Θ and angle Φ.
