TlBr is considered an excellent gamma-ray detection material because of its high atomic number and density and room temperature operation. The coplanar structure is promising as a structure that can achieve both high energy resolution and sensitive volume, but leakage current due to potential difference is a problem. Therefore, we proposed an unbiased coplanar structure and investigated these issues.
