Ihe Akụkụ Abụọ

Ngwa nke ihe 2D

A mụọla graphene na ihe akụkụ abụọ (2DM) na sayensị na injinịa ihe fọrọ nke nta ka ọ bụrụ afọ 20 kemgbe mbụ a tụrụ aro ha. Akụ na ụba nke data dị na ihe ngosi ngwaọrụ dị elu na-eme ka enweghị obi abụọ ọ bụla maka ike nke 2DM maka ngwa na ngwá electronic, optoelectronics na sensing.

Yabụ kedu isi ihe ịma aka na ohere dị na ịnakwere ihe 2D maka ngwa? Nkà na ụzụ dị ugbu a egosila na ihe 2D nwere ike iji uru nke arụmọrụ ha dị elu na ọkwa ngwaọrụ semiconductor ma nwee ike ịmekọrịta ngwa ngwa na teknụzụ ndị ọzọ semiconductor, na-eme ka ha bụrụ ndị na-aga maka nnukwu ọrụ agbatị na ihe semiconductor.

Mpụta nke ihe 2D na-enye ụzọ ọhụrụ iji mebie njedebe dị iche iche na arụmọrụ nke ngwaọrụ semiconductor, ma na-enye echiche ọhụrụ maka ịghọta ngwa ọrụ dị iche iche. Anyị kwenyere na ihe 2D ga-aghọwanye ihe x-factor na ngwaahịa agbakwunyere semiconductor n'ọdịnihu, dabere na ngwa ebumnuche, yana na a ga-agbaji ihe mgbochi dị na ngwa elektrọnik dị iche iche dabere na ihe 2D ruo n'ogo achọrọ nke nrụpụta nnukwu.
