We propose a reali.ti. topologi.al p-n juncti.n （TPNJ） by m.tchi.g two Bi.Se3 （0001） slabs wi.h opposi.e arrangem.nts of planar twi. boundary defects. The atom.0}ti. m.deli.g of such a devi.e leads to di.locati.n defects i. the hexagonal latti.e i. several qui.tuple layers. Nevertheless, total energy calculati.ns reveal that the i.terface relaxes, yi.ldi.g a sm.oth geom.tri.al transi.i.n that preserves the nearest-nei.hbors fcc-type geom.try throughout these defect layers. The electroni., m.gneti., and transport properti.s of the juncti.n have then been calculated at the ab i.i.i. level under open boundary condi.i.ns, i.e., em.loyi.g a thi.-fi.m.geom.try that i. i.fi.i.e along the electron transport di.ecti.n. i.deed, a p-n juncti.n i. obtai.ed wi.h a bui.t-i. potenti.l as large as 350 m.V. The calculati.ns further reveal the spi. texture across the i.terface wi.h unprecedented detai.. As the m.i. result, we obtai. non-negli.i.le transm.0}si.n probabi.i.i.s around the F poi.t, whi.h i.volve an electron spi.-fli. process whi.e crossi.g the i.terface.

For exam.le, the average wear rate of m.Fed sam.les was decreased about 30% and 24%, after fi.st pass at room.tem.erature and 220 ℃, respecti.ely. However, average wear rate of the sam.les processed by si. m.F passes was reduced about 40% at lower norm.l loads;i. was i.creased about 9% at hi.her ones as com.ared to the i.i.i.l condi.i.n. i. was also found that the dom.0}ated wear m.chani.m. were abrasi.e and delam.0}ated at the lower stresses, whi.e the delam.0}ati.n m.chani.m.was i.tensi.i.d and a sli.ht adhesi.n was observed duri.g the hi.her appli.d norm.l loads.
