A paper pakhat zawkah chuan Ge1-xSnx quantum heterostructure chhunga atom inremkhawm dan a zir chian chu a present a. Molecular Beam Epitaxy hmanga quantum heterostructure nei tura atom an remkhawm dan te, tin, a bik takin temperature hniam lutuk atom an rem avanga thil lo danglam bik dan te leh Atom te chu tha chakna, entirnan lumna hmanga tha an pekin engtin nge an lo danglam tih a zirchianna chu a zu present a ni.

Pakhat zawkah chuan Ge1-xSnx chu quantum well anga siamin a chhah zawng chu de Broglie wavelength (kan hriatthiam theih nan electron wavelength a ni ber mai) ang leka panin Molecular Beam Epitaxy hmangin atom chu temperature hniam lutukah an remkhawm leh a. Chutah chuan electron emaw exciton emaw chu mihringte anga dimension thum khawvela awm thin kha dimension hnihah chauh an awmtir a. An energy zir tur pawhin quantum mechanics takin zir a lo ngai a, a hmaa energy continuous nei thin kha a lo bung (discrete/quantize) ta a. Chumi avang chuan an energy density states pawh grapah kan plot chuan step angin a lo awm ta a ni. Chu chuan tangkaina tam tak a nei a. Atomic scale transport properties lama a nghawng dan te, eng lam (optical properties) lama thil tha zawk a thlen theih dan leh mihringte’n kan hman tangkai theih dan tur, Kris-a’n a zir chianna leh mi tihdik loh lai nia a hmuhchhuahte chu a present a ni.

A thil zir chian tharte leh mi zir chian dan fuh chiah lo nia a hmuhchhuahte chu tha takin a present a.

Sikul a kal tawhna apiangah sikul tihmingthatu a ni zel a. Exam-naa a tihthat piah lamah Quiz competition, Science Seminar leh a dang tam takah a kal tawhna sikul a lo champion-pui tawh thin. National Children Science Congress-ah phei chuan Baptist Higher Secondary School (BHSS), Boys Hostel-a an tui hman dan a zir chianna chu A++ grade a lo hmuhpui tawh a. He grade hi North East-ah chuan hmu hmasa ber leh awmchhun a ni.

College zir tuma a intintuah laiin chhungkaw khawsak harsat avangin a inngaihtuah buai hle. Chutih laiin Rev. V. Lalhmingsanga chuan Aizawl-a a inhlawhna tur a ngaihtuahsak thei hlauh va, chu thu chu class XII Board exam laiin a hria a, a lawm ngei mai! Tichuan, pawl 12 result a nghah chhungin Bee Zet HSS, Bawngkawn-ah a thawk ta a, Govt. Zirtiri Residential College-ah inziak lutin, a tirah Physics la zet mah se, a hma lam hun atana tha zawk dawna a hriat avangin Mathematics honours-ah a inlet leh a ni. Sikula thawk chungin 1st year chu a zir tluan a. 2nd year a zir kumah Donbosco Higher Secondary lamah a thawk leh a. Sikula thawk chunga college kal a nih avangin zirtirtute zirtirna chu a dawng tlem em em a, mahse, hun awl a neih chhun chhun chu library-ah hmangin lehkhabu chhiar nan a hmang thin a ni.

Tunah pawh hian khawvel pum huap pawha hmanraw vang leh changkang, Molecular Beam Epitaxy khawih thei tlemte zingah a tel a, chu mai ni lovin Molecular Beam Epitaxy research group mi 5 chauh awmna chu amahin a ho va, group leader a ni mek a ni. Tin, IIT Bombay a hmanraw changkang leh to em em, mi tlemte chauhin an khawih theih, High Resolution TEM (atomic position precise taka enna), High Resolution XRD (atomic plane zir chian nana hmanraw tha ber)-ah te hian a khawih theitu tlemte zinga a tel mai ni lovin a thu berte zingah leh a expert ber a ni thei ngat a ni. Tunah hian IIT Bombay Post Graduate Academic Council member a ni mek  a, a vai thiante zah a kai a, a thu an ngaichang thin a, institution level-ah pawh a larin mi hriat a hlawh hle. Seminar leh conference huaihawt velnaa pawh research scholars aiawhin convener a ni thin. Tunah hian hman atanga a lo suangtuah thin Ph.D a zir mek a ni.

“Ka zirlai puite thurawn ka pek duh che u chu – Pathian tih tlat la, A duh dana i awm chuan Ani pawhin I duh chu a hriatpui reng ang che,” tiin Mizo zirlaite a chah a ni.
