Enweghị nkà na ụzụ njikwa ọkụ kwesịrị ekwesị, na mgbakwunye na ibelata ọsọ ọrụ nke onye nrụpụta na ibelata ntụkwasị obi, enwerekwa ihe kpatara na-egbochi oke ọkụ ma na-achọ ume ọzọ, na-emepụta nsogbu enweghị ike ike. Iji dozie nsogbu a, Mahadum California, Los Angeles mepụtara ihe ọhụrụ semiconductor na 2018 dị oke elu, nke nwere boron arsenide na boron phosphide na-enweghị ntụpọ, nke yiri ihe na-ekpo ọkụ dị ugbu a dị ka ihe na-ekpo ọkụ. diamond na silicon carbide. ruru, na ihe karịrị 3 ugboro thermal conductivity.
Na June 2021, Mahadum California, Los Angeles, jiri ihe semiconductor ọhụrụ jikọtara ya na ibe kọmpụta dị elu iji gbochie ọgbọ okpomọkụ nke ibe ahụ nke ọma, si otú a na-emeziwanye arụmọrụ kọmputa.

Mgbe ejikọtara mkpụrụ osisi boron arsenide na nnukwu oghere ike gallium nitride semiconductor, akwadoro na nrụpụta ọkụ nke gallium nitride/boron arsenide interface ruru 250 MW/m2K, na nguzogide thermal interface ruru obere ọkwa. Ngwakọta boron arsenide na-ejikọta ya na mgbawa transistor dị elu dị elu nke nwere aluminom gallium nitride/gallium nitride, a na-ekwenyekwa na mmetụta ikpo ọkụ ọkụ dị mma karịa nke diamond ma ọ bụ silicon carbide.
Ndị otu nyocha na-arụ ọrụ mgbawa na ike kachasị, wee tụọ ebe dị ọkụ site na ọnụ ụlọ ruo na okpomọkụ kachasị elu.
