Cov pa roj carbon nanotubes tau pom lwm daim ntawv thov. Ob peb hnub dhau los, ib tsab xov xwm tau luam tawm nyob rau hauv phau ntawv journal Nature Scientific Reports uas thawj zaug tau txiav txim siab muaj peev xwm siv Multiwall carbon nanotubes (MWCNT) hauv cov ntaub ntawv sib nqus ntawm cov tsav nyuaj. Cov no yog ntau yam ntawm CNT cov qauv nyob rau hauv daim ntawv ntawm "matryoshka menyuam roj hmab", "convolutions" thiab lwm yam qauv. Cov haujlwm hauv txhua kis los rau ib qho - mus rau txhua yam uas zoo li cov carbon nanotube nrog sib nqus nanoparticles. Txhua qhov sib nqus nanoparticle cais yuav tsis tsim cov ntaub ntawv kaw tseg. Koj tsuas tuaj yeem hloov qhov kev sib nqus ntawm tag nrho cov raj, tab sis nws tseem yuav denser dua li kev sau npe sib nqus ntawm cov hlau nplaum HDD tsis tu ncua. Ntau denser.
Txoj kev tshawb fawb ntawm cov ntaub ntawv sib nqus ntawm MWCNT tau ua los ntawm cov kws tshawb fawb los ntawm University of Alaska (Fairbanks) thiab ntau lub tsev kawm tshawb fawb hauv Asmeskas thiab Czech koom pheej. Ib tus thawj coj ntawm qhov project yog tus kws tshawb fawb Czech Gunther Kletetschka. Tus kws tshaj lij sau tseg tias cov txheej txheem uas twb muaj lawm los ua kom cov ntaub ntawv ceev ceev ntawm HDD sib nqus disks tsis sib haum rau qhov ceev ntawm cov ntaub ntawv loj hlob. Txhawm rau tiv thaiv kev loj hlob ntawm cov ntaub ntawv, qhov ceev ceev ntawm hard drives yuav tsum loj hlob los ntawm 40% txhua xyoo, thiab nyob rau hauv xyoo tas los nws tau loj hlob los ntawm 10-15% ib xyoos twg. Kev sau cia siv cov pa roj carbon hlau nplaum yuav yog cov lus teb rau cov teeb meem ntawm cov ntaub ntawv hnub nyoog, tab sis kev tshawb fawb loj heev tseem yuav tau ua rau qhov no.
Lub ntsiab lus ntawm qhov kev tshawb pom yog tias cov pa roj carbon nanotubes nrog cov hlau nplaum nanoparticles sab hauv tau raug rau electromagnetic teb ntawm txawv amplitudes thiab txawv frequencies. Los ntawm txoj kev, zus tau tej cov carbon tubes khoom nrog nanoparticles yog nqa tawm siv deposition nyob rau hauv ib tug gaseous ib puag ncig - tsis muaj dab tsi tshiab. Thaum lub magnetic teb tau thov nrog ntau zaus txog li 10 kHz, tsis muaj dab tsi tshwm sim (qhov cuam tshuam ntawm cov pa roj carbon nanotubes cuam tshuam), tab sis nrog kev nce ntau zaus tshaj 10 kHz thiab nrog kev txo qis hauv thaj chaw amplitude, cov nyhuv ntawm magnetization ntawm ib tug carbon nanotube nrog magnetic nanoparticles tshwm sim. Raws li cov kws tshawb fawb, sab nraud teb tau pom zoo nrog cov hlau nplaum ntawm ib tus neeg hais, uas ua rau nws muaj peev xwm muab cov nanotube ruaj khov magnetization nyob rau hauv ib qho kev taw qhia.
Cov kws tshawb fawb tseem tsis tau muaj lus pom zoo txog yuav ua li cas thiab yuav ua li cas los tsim cov ntaub ntawv kaw lus thiab nyeem cov txheej txheem rau kev sau cov ntaub ntawv ntawm cov pa roj carbon nanotubes, tab sis lawv cog lus tias yuav ua haujlwm zoo hauv cov lus qhia no, vim tias dhau sijhawm yuav tsis muaj cov ntaub ntawv tsawg dua.
