In cha.cogenide top.logica. insula.or ma.eria.s, two typ.s of ma.netoresista.ce （MR） effects a.e widely discussed： a.sha.p.MR dip.a.ound zero ma.netic field, a.socia.ed with the wea. a.tiloca.iza.ion （Wa.） effect, a.d a.linea. MR （LMR） effect tha. genera.ly p.rsists to high fields a.d high temp.ra.ures. We ha.e studied the MR of thin films of the top.logica. insula.or Bi2Te3 from the meta.lic to semiconducting tra.sp.rt regime. In the meta.lic sa.p.es, the Wa. is difficult to identify owing to the low ma.nitude of the Wa. comp.0}ed to the sa.p.es＇ conductivity. Furthermore, the sha.p.Wa. dip.in the MR is dea.ly p.esent in sa.p.es with a.higher resistivity. To correctly a.count for the low-field MR with the qua.tita.ive theory of the Wa. a.cording to the Hika.i-La.kin-Na.a.ka.（HLN） model, we find tha. the cla.sica. （linea.） MR effect should be ta.en into a.count in combina.ion with the Wa. qua.tum correction. Otherwise, the Wa. fitting a.one yields a. unrea.istica.ly la.ge coefficient in the HLN a.a.ysis. This work cla.ifies the Wa. a.d LMR a. two distinct effects a.d offers a. exp.a.a.ion for the overly la.ge a.in the Wa. a.a.ysis of top.logica. insula.ors in some studies.
