• projected to reach 200.000 tons per year by 2025 while the current annual supply is estimated to be only 113.000 tons. The attempt to increase the REE supply at a rate sufficiently high to meet the increase in demand faces economic, political and environmental limitations [4][5]. Over 95% of the global REE

• manufactured by using a combination of photolithography and etching: First a 200 nm thick nickel layer was deposited on a microscope glass slide by a standard evaporation technique. A layer of negative photoresist (SU-8 2025, Microchem, adhesion promoter TI Prime, Microchemicals GmbH) was spin-coated onto the
