### Description

The Advanced Mo-based Rare process Experiment (AMoRE) is an international collaboration searching for the neutrinoless double-beta decay of 100Mo using molybdenum-based scintillating crystals with metallic magnetic calorimeters (MMC). The collaboration is preparing for phase-II of the experiment in which lithium molybdate(Li$_2$MoO$_4$) crystals will be the main target meterial. We have made lots of efforts to optimize the detector performance and detector preparation procedure to provide hundreds of detectors in a good timely manner without sacrificing the detector performance. We have developed the detectors under various experimental conditions, which include the humidity, crystal size, surface treatment, thermal connection. In this poster, we will present how the detector performances improved in terms of the energy resolution and the alpha background separation based on the ratio of heat/light channel signals and the signal pulse shape in the detector R&D campaign.
