Viljams Šoklijs (angļu: William Bradford Shockley Jr., dzimis 1910. gada 13. februārī, miris 1989. gada 12. augustā) bija ASV fiziķis un izgudrotājs. 1956. gadā Šoklijam kopā ar Džonu Bardīnu un Volteru Brateinu tika piešķirta Nobela prēmija fizikā par viņu pusvadītāju pētījumiem un tranzistora efekta atklāšanu.

Biogrāfija

Kopš 1945. gada Šoklijs bija Bell Labs izpētes grupas vadītājs, kurā bija Džons Bardīns un Volters Brateins. Pēc Bell Labs izpētes grupas izjukšanas, 1956. gadā Šoklijs pārvācās no Ņūdžersijas uz Kaliforniju, kur izveidoja savu pusvadītāju ražotni Shockley Semiconductor Laboratory, kur viņš strādāja pie jaunu tranzistoru izstrādes komercializācijas. Šoklija uzņēmums, kas bija Beckman Instruments, Inc. nodaļa, bija pirmais tāda tipa uzņēmums, kas strādāja ar pusvadītāju ierīcēm tā sauktajā Silīcija ielejā. Vēlāk daži no viņa darbiniekiem paši izveidoja savus uzņēmumus.

Džons Bardīns, Viljams Šoklijs un Volters Brateins Bell Labs, 1948. gads

Daļēji pateicoties Šoklija mēģinājumiem komercializēt jaunu tranzistora dizainu 20. gadsimta piecdesmitajos un sešdesmitajos gados, Kalifornijas Silīcija ieleja kļuva par elektronikas inovāciju rašanās vietu. Savā turpmākajā dzīvē, no 1958. gada Šoklijs bija Stenfordas Universitātes elektroinženierijas profesors, kur viņš arī kļuva par aktīvu eigēnikas teorijas atbalstītāju.

ASV patentēti vairāk nekā 90 Šoklija izgudrojumi.
