Conclusions and outlook.This book highlights the origin of low external quantum efficiency for deep ultraviolet light-emitting diodes (DUV LEDs). In addition, it puts forward solutions for increasing the internal quantum efficiency and the light extraction efficiency of DUV LEDs. The book chiefly concentrates on approaches that can be used to improve the crystalline quality, increase carrier injection, reduce the polarization-induced electric field within multiple quantum wells, suppress the TM polarization emission, and enhance the light escape from the semiconductor layer. It also demonstrates insightful device physics for DUV LEDs, which will greatly benefit the optoelectronic community.Nanoscience and Nanotechnology,2196-1670Optical materialsMicrowavesOptical and Electronic Materialshttp://scigraph.springernature.com/things/product-market-codes/Z12000Microwaves, RF and Optical Engineeringhttp://scigraph.springernature.com/things/product-market-codes/T24019Optics, Lasers, Photonics, Optical Deviceshttp://scigraph.springernature.com/things/product-market-codes/P31030Signal, Image and Speech Processinghttp://scigraph.springernature.com/things/product-market-codes/T24051Optical materials.Microwaves.Optical and Electronic Materials.Microwaves, RF and Optical Engineering.Optics, Lasers, Photonics, Optical Devices.Signal, Image and Speech Processing.620.11295620.11297Zhang Zi-Huiauthttp://id.loc.gov/vocabulary/relators/aut875253Chu Chunshuangauthttp://id.loc.gov/vocabulary/relators/autTian Kangkaiauthttp://id.loc.gov/vocabulary/relators/autZhang Yonghuiauthttp://id.loc.gov/vocabulary/relators/autBOOK9910350303903321Deep Ultraviolet LEDs1954057UNINA04448 am 2201033 n 450 991049567690332120200131979-1-03-000633-910.4000/books.pub.18278(CKB)4100000011289053(FrMaCLE)OB-pub-18278(oapen)https://directory.doabooks.org/handle/20.500.12854/86093(PPN)248497847(EXLCZ)99410000001128905320200608j|||||||| ||| 0freuu||||||m||||txtrdacontentcrdamediacrrdacarrierLa forêt romantique /Victor CailletPessac Presses Universitaires de Bordeaux20201 online resource (280 p.) Eidôlon979-1-0910-5203-0 Ce volume étudie les représentations romantiques de la forêt au xixe entre romantisme et positivisme mais aussi entre romantisme et décadentisme autour de plusieurs pistes et questions. Il s’attache à dégager à travers tout le xixe les continuités, les ruptures, les modulations, les détournements voire les retournements. La forêt est un espace sauvage certes ; mais en même temps elle est un paysage en perpétuelle évolution : elle n’échappe pas à l’économie. Les écrivains, Balzac et Sand, par exemple, enregistreront ces mutations. La forêt se sépare en deux espaces : celui des cultures (de la culture), celui de la nature. Le couple est sans cesse interrogé dans ce volume. L’attachement romantique à la forêt n’est pas seulement l’expression d’une nostalgie. Il est également porteur des embryons d’une pensée que nous qualifierions aujourd’hui « d’écologiste ». Ce livre, qui regroupe une vingtaine de contributions, part de l’évidence romantique apparente selon laquelle le moi est lié à la forêt. La force de cette relation privilégiée est ensuite examinée, qui s’explique aussi bien par les enchantements que par les chants offerts par et dans la forêt. Examiner ensuite comment la réalité sylvestre, celle de Fontainebleau, en particulier, qui a conquis de grands écrivains de l’époque, hante et nourrit tout à la fois l’imaginaire fantasmatique, permet d’aborder pour finir la forêt dans sa dimension iconographique. Le livre se clôt sur un magnifique portfolio photographique.Literature (General)cultureécologieromantismeimaginairereprésentationiconographieéconomiepositivismeforêtnaturesauvagerienostalgiecultureécologieromantismeimaginairereprésentationiconographieéconomiepositivismeforêtnaturesauvagerienostalgieLiterature (General)cultureécologieromantismeimaginairereprésentationiconographieéconomiepositivismeforêtnaturesauvagerienostalgieBaudoin Sébastien1291969Botterel-Michel Catherine1291970Caillet Vigor1283955Chelebourg Christian185069Cise Barbara1291971Dufief Pierre-Jean176849Feyler Patrick1289425Guillaud Lauric1279290Guillou Alan1291972James-Raoul Danièle1283404Laffont Laurent-Jocelyn1291973Laurent Jérôme1291974Leray Morgane1291975Le Scanff Yvon1291976Madriasse Sébastien1291977Mansau Andrée172982Marié Liger Fabienne1285720Reid Martine421645Saule-Sorbé Hélène1291978Caillet Victor1291979FR-FrMaCLEBOOK9910495676903321La forêt romantique3022104UNINA04409nam 22006135 450 991064039930332120251008161948.09783031240454303124045610.1007/978-3-031-24045-4(CKB)5720000000120042(oapen)https://directory.doabooks.org/handle/20.500.12854/96232(MiAaPQ)EBC7175171(Au-PeEL)EBL7175171(OCoLC)1369649790(DE-He213)978-3-031-24045-4(PPN)267812876(ODN)ODN0010068561(EXLCZ)99572000000012004220230109d2023 u| 0engurmn|---annantxtrdacontentcrdamediacrrdacarrierEntrepreneurial Theorizing An Approach to Research /by Dean A. Shepherd, Holger Patzelt1st ed. 2023.Cham :Springer International Publishing :Imprint: Palgrave Macmillan,2023.1 electronic resource (210 p.)9783031240447 3031240448 Chapter 1: Theorizing And Entrepreneurship -- Chapter 2: Me-Search For Generating Ideas for Entrepreneurial Theorizing -- Chapter 3: Anthropomorphizing for Entrepreneurial Theorizing -- Chapter 4: Managing Trade-Offs in Entrepreneurial Theorizing -- Chapter 5: Writing Entrepreneurial-Theorizing Outcomes -- Chapter 6: A Lean Approach to Entrepreneurial Theorizing.This open access book investigates an entrepreneurial approach to building new theories. It provides a rich understanding of how specific tools facilitate aspects of the theorizing process and offers a clearer big picture of the process of building important new entrepreneurship theories. The authors show that anthropomorphizing has been a critically important tool for developing influential entrepreneurship theories. They reveal how scholars build on their rich and highly accessible understanding of humans (i.e., the self and others) to make guesses and sense of entrepreneurial anomalies, articulate theoretical mechanisms to build more robust entrepreneurship theories, and create plausible stories that facilitate sensegiving. Further, they offer a frameworkthat guides entrepreneurship scholars in finding a balance to maximize their contributions and guides reviewers and editors in managing the revise-and-resubmit process to advance the entrepreneurship field. Finally, they present lean scholarship as an approach to developing a portfolio of high-quality, high-impact papers. Lean scholarship starts with an entrepreneurial mindset and involves creating a minimum viable paper, exploring its validity, adding a plausible paper to one’s portfolio, and managing the portfolio by periodically deciding whether to persevere, pivot, or terminate each paper. This seminal work will appeal to entrepreneurship researchers, both those new to the field as well as seasoned veterans, who want to learn more about the tools that can be used to generate new knowledge about new ventures and other entrepreneurship topics.
