Enwere ike ekewa semiconductor ụzọ abụọ, otu dabere na ụkpụrụ i-ection nke semiconductor Pn Junction (ma ọ bụ Schottky Junction) mgbanwe n'okpuru nrụgide. Nrụpụta nke ihe a nrụgide na-enweghị atụ na emebeghị nke ukwuu. Nke ọzọ bụ ihe mmetụta dị na semiconductor si na semiconductor mmetụta, nke bụ ihe dịgasị iche iche nke semiconductor nrụgide nrụgide. N'oge izizi, a na-ejikọ semiconductor ga-enwekarị ihe dị iche iche na-agbanwe agbanwe iji mee ka nchekasị dị iche iche ma na-eji ihe na-eji ihe na-eji ihe. N'afọ 1960, site na mmepe nke semiconductor ike sekit, ihe mmetụta semiconductor na ngbanwe na-emegide ya dị ka ihe dị iche iche yiri.

Mmetụta Simezuesisive Mmetụta Semiconductor nwere njiri mara nke ike, ya bụ, na-adịgide ma ọ bụ na-anọchi anya nrụgide ọ na-enwe, nke a na-akpọ piagoreesive mmetụta. A na-akpọ mgbanwe nke iguzogide n'okpuru ọrụ nrụgide nke otu na-akpọ paizoresilitive coeffictive, nke akara na-egosipụta ya site na akara π. Kwupụtara mgbakọ na mwepụ dị ka ρ / ρ = π σ.

Ebe σ na-anọchi anya nrụgide. Mgbanwe nke nguzogide (R / R) kpatara nguzogide na-eguzogide n'okpuru nchebisi ike site na mgbanwe nke iguzogide ya site na mgbanwe nke iguzosi ike dika r / r = πσ.

N'okpuru omume nke ike mpụga, ụfọdụ nchekasị (σ) na nje (σ) na-ezute na Cristal, na modus nke na-eto eto (Y) nke ihe ahụ, nke ahụ bụ, σ = σ / σ / σ / σ / σ / σ / σ / σ / σ / σ / σ / σ / σ / σ / σ.
