Title: Maritza G Heijman: Innovator in Superconductive Materials

Introduction

Maritza G Heijman is a prominent inventor based in Eindhoven, Netherlands. She has made significant contributions to the field of superconductive materials, holding a total of 5 patents. Her innovative work focuses on methods for patterning superconductive oxide films, which are crucial for advancing technology in various applications.

Latest Patents

One of her latest patents is titled "Method of patterning superconductive oxide films by use of diffusion." This method involves manufacturing a device that includes a film of an oxide superconducting material, which consists of an alkaline earth metal, another metal component, copper, and oxygen. The process begins with providing a superconductor precursor material on a substrate in the form of a film. This film is then covered with a diffusion barrier against water, following a pattern that complements the desired superconducting material. The superconducting material is subsequently formed in the uncovered portions through a treatment at elevated temperatures in the presence of water and oxygen.

Another notable patent is "Method of patterning superconducting oxide thin films." This method describes the application of thin layers of an oxidic superconductive material onto a substrate. A copper oxidic-based material, which becomes superconducting after heating, is covered in a desired pattern with a composition that renders the underlying oxidic material non-superconducting.
