“…Several experiments are focusing on different isotopes via utilizing various detector techniques such as GERDA (GERmanium Detector Array) [4], MAJORANA (Majorana Demonstrator) [5] and CDEX (China Dark matter EXperiment) with 76 Ge enrich high purity Ge detectors [6]; EXO (Enriched Xenon Observatory) [7] and KamLandZen (Kamioka Liquid Scintillator Antineutrino Detector) with liquid 136 Xe time projection chambers [8]; and CUORE (Cryogenic Underground Observatory for Rare Events) with 130 Te bolometric detectors [9]. The next-generation experiments with tonne scale detectors such as LEGEND ( 76 Ge) (MAJORANA + GERDA) [10,11], nEXO ( 136 Xe) [12], NEXT ( 136 Xe) [13], CUPID ( 130 Te) [14], SuperNEMO ( 82 Se, 150 Nd) [15], AMoRE ( 100 Mo) [16], COBRA ( 116 Cd) [17], CANDLES-III ( 48 Ca) [18], SNO + ( 130 Te) [19], TIN.TIN ( 124 Sn) [20], MOON ( 100 Mo) [21] and LUMINEU ( 100 Mo) [22] have been proposed. Some of them will start data taking over the next few years and others are under construction phase.…”
