Item type:Publication, Access status: without files , On the combination of pyrolysis and plasma to create Parylene C thin films(VDE Verlag, 2025); ; ; ; Pyrolysis for Parylene C deposition is a safe way to produce biocompatible hermetic thin films above 1 µm. For thin films below that thickness, the use of plasma is a well-researched process, but these films lack biocompatibility. With the combination of pyrolysis and Argon-plasma (30 W, 50 W), a new process was used to create Parylene C thin films and investigate thickness, Young’s Modulus, FTIR spectra, and the surface via SEM. The use of 50 W Argon-plasma shows an increase of thickness (1.6 µm) and Young’s Modulus (26.34 GPa) compared to pyrolysis (t=0.9 µm, E=7 GPa).Publicationtype: Conference Paper97 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , On the applicability of the Maxwell Garnett effective medium model to media with a high density of cylindrical pores(Optica Publishing Group, 2024-04-01); ; ; ; The optical properties of dielectric materials with subwavelength cylindrical pores are commonly described by effective medium models. We compare the Maxwell Garnett and the Bruggeman effective medium models for porous silicon with simulations and experiments for the case of polarization orthogonal to the pore axis. The Maxwell Garnett model matches the results of the simulations even up to very high porosities. An experimental study of the effective permittivity of macroporous and mesoporous silicon is conducted by analyzing the Fabry-Pérot oscillations in the long-wavelength limit. These experimental results are also consistent with the Maxwell Garnett model. We advocate using this model for media with cylindrical pores in the future.Publicationtype: Journal Article36 56 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Maxwell Garnett effective medium model for dielectric materials with high filling fraction of cylindrical poresThe optical properties of dielectric materials with subwavelength cylindrical pores are commonly described by effective medium models. We compare the Maxwell Garnett and the Bruggeman effective medium model for porous silicon with simulations to study their applicability. We found that the Maxwell Garnett model matches the results of the simulations even up to high porosities and discuss the reasons for this. We advocate using this model for membranes with cylindrical pores in the future.Publicationtype: Conference Paper45
