Abstract ZnO is a widely used metal-oxide semiconductor for photovoltaic application. In solar cell heterostructures they not only serve as a charge selective contact, but also act as electron acceptor. Although ZnO offers a suitable interface for ex

In this paper, the usability of the classical Harmonic Balancing method (cHB) to calculate the weakly nonlinear motion of phase- and amplitude controlled MEMS resonators is demonstrated. A polynomial mechanical stiffness description and linearized el

The operation range of today’s micro-electromechanical systems (MEMS) continues to enter the geometric nonlinear regime due to miniaturization and performance requirements. One example is the MEMS Coriolis Vibratory Gyroscope (CVG), where the drive

MEMS acceleration sensors have been systematically analyzed across a wide temperature range between -40°C and +85°C. Failure mechanisms such as offset drift induced by thermal mismatch of different materials are well understood. However, in densely

Due to manufacturing uncertainties and due to geometric constraints on the moving structure, the drive mode of MEMS gyroscopes may exhibit high intrinsic nonlinearity [1,5]. The type of the drive mode nonlinearity is mainly quadratic in amplitude [5,

We compare different simulation methods for the development of reduced order models (ROM) that feature a geometric nonlinear drive motion in a MEMS device. We benchmark three different simulation methods by comparing the results to measured frequency

Hybrid nanostructures have shown increasing potential as a replacement for Si solar cells due to the availability of low-cost material combinations. However, up to now, hybrid solar cells, where photon absorption occurs in a semiconducting polymer an
