This was measured using photo excited capacitance as a function of applied voltage bias. Resonant tunneling in this heterostructure definitely requires momentum space narrowing of charge carriers inside the quantum well and that of associated indirect excitons, which indicates bias dependent ‘itinerant’ Bose-Einstein condensation of excitons. Observation of periodic variations in negative quantum capacitance points to in-plane coulomb correlations mediated by long range spatial ordering of indirect, dipolar excitons. Enhanced contrast of quantum interference beats of excitonic polarization waves even under white light and observed Rabi oscillations over a macroscopically large area also support the presence of density driven excitonic condensation having long range order. Periodic presence (absence) of splitting of excitonic peaks in photocapacitance spectra even demonstrate collective coupling (decoupling) between energy levels of the quantum well and quantum dots with applied biases, which can potentially be used for quantum gate operations. All these observations point to experimental control of macroscopically large, quantum state of a two-component Bose-Einstein condensate of excitons in this quantum dot - quantum well heterostructure. Therefore, in principle, millions of two-level excitonic qubits can be intertwined to fabricate large quantum registers using such hybrid heterostructure by controlling the local electric fields and also by varying photoexcitation intensities of overlapping light spots.</p></div>","PeriodicalId":100893,"journal":{"name":"Materials Today Electronics","volume":"4 ","pages":"Article 100039"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49884415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this letter, a disruptive common-channel reconfigurable filed effect transistor concept is presented experimentally for the first time. A cross-shape integrated nanowire structure is fabricated on a silicon-on-insulator wafer using top-down methods for higher reproducibility. The fabricated cross-shape reconfigurable field effect transistor is composed of a doping-free common channel with four independent silicided source and drain junctions, a silicon dioxide dielectric layer and four independent gates aligned on top of the silicide junctions. By assembling this unique common-channel structure, device level current routing was provided. A detailed comprehensive study of the cross-shape reconfigurable field effect transistor electrical characteristics are presented. The fabricated device demonstrates nearly equal transistor characteristics for each branch, which enables new complementary circuit designs to be introduced.
