A research team, led by Professor Dai-Sik Kim in the Department of Physics at UNIST has developed a new technique of predefining the crack pattern on a flexible substrate by a sequential deposition of metallic layers which leads to a formation of a'”zero-nanometer gap’, or a ‘zerogap,’ between the adjacent lateral patterns.
