Opis:: Tomography is a useful tool for objects reconstruction in non-destructive testing. Many kinds of tomography, depending on the penetrating wave character, are available and adapted for specific application. This paper presents new kind of tomography - conductance tomography extended with a Hall effect. Its development was motivated by the need on inhomogeneity detection in thin film Hall effect sensor, particularly graphene Hall effect sensors. Paper presents complete description of the tomographic method and tomography software developed in the GNU Octave. Inverse transformation is based on optimization method. Each shape reconstruction was done with the finite element method using the open source software: Elmer FEM and Salome. Results confirmed the suitability of the work.

Opis:: The paper presents numerical model and validation of new methodology of offset voltage minimization in the Hall-effect sensors. Model of the Hall-effect sensor with multiple electric pins was developed. Mathematical equations used for calculation of electric potential difference were formulated. Simulations were carried out using finite elements method in ELMER FEM software. Performed investigation of actual parameters of newly designed Hall-effect sensor confirms effectiveness of the described method.

Opis:: The paper describes the design, development, and investigation of a new type of Hall-effect sensors of a magnetic field made of graphene. The epitaxial growth of high-quality graphene structures was performed using a standard hot-wall CVD reactor, which allows for easy integration with an existing semiconductors production technologies. The functional properties of developed Hall-effect sensors based on graphene were investigated on special experimental setup utilizing Helmholtz coils as a source of reference magnetic field. Monolayer and quasi-free-standing bilayer graphene structures were tested. Results presented in the paper indicate that graphene is very promising material for development of Hall-effect sensors. Developed graphene Hall-effect sensor exhibit highly linear characteristics and high magnetic field sensitivity.
