I-Ultraviolet superdetector

Isitholi se-quantum semisebe ye-ultraviolet enokuzwela okurekhodiwe - esakhiwe ososayensi abavela e-American McCormick School of Engineering. Ukushicilelwa ngalesi sihloko kuvele kumagazini wakamuva wephephabhuku lesayensi elithi “Letters on Applied Physics”.

Lolu hlobo lomtshina lungaba usizo kakhulu uma sifuna ukubona ukuhlaselwa kwemicibisholo nezikhali zamakhemikhali nezebhayoloji kusenesikhathi. Kokubili izinjini zezindiza nezamarokhethi zikhipha amaza ebangeni le-ultraviolet, afana ne-infrared. Kodwa-ke, izitholi ze-UV zingaba usizo lapho i-infrared ingasebenzi, njengokukhanya kwelanga, umehluko omncane wezinga lokushisa, njll.

Uhlobo olusha lomtshina olwakhiwe ososayensi kufanele lusebenze kahle ngama-89%. Kuphinde kwaba nokwenzeka ukwenza inguqulo eshibhile yomtshina esekelwe ku-silicon esikhundleni samadivayisi asekelwe esafire ngokuvamile asetshenziswa kulolu hlobo lwedivayisi.
