Initial demonstration of AlGaAs-GaAsP-beta-Ga2O3 n-p-n double heterojunctions
Beta phase gallium oxides, an ultrawide-bandgap semiconductor, has great
potential for future power and RF electronics applications but faces challenges
in bipolar device applications due to the lack of p-type dopants. In this work,
we demonstrate monocrystalline AlGaAs_GaAsP_beta phase gallium oxides n-p-n
double-heterojunctions, synthesized using semiconductor grafting technology. By
transfer printing an n-AlGaAs_p-GaAsP nanomembrane to the n-beta
phase-GaO epitaxial substrate, we simultaneously achieved AlGaAs_GaAsP
epitaxial n-p junction diode with an ideality factor of 1.29 and a
rectification ratio of 2.57E3 at +/- 2 V, and grafted GaAsP_beta_phase_gallium
oxides p-n junction diode exhibiting an ideality factor of 1.36 and a
rectification ratio of 4.85E2 at +/- 2 V.Comment: 12 pages, 4 figure
Demonstration of a monocrystalline GaAs--GaO p-n heterojunction
In this work, we report the fabrication and characterizations of a
monocrystalline GaAs/-GaO p-n heterojunction by employing
semiconductor grafting technology. The heterojunction was created by lifting
off and transfer printing a p-type GaAs single crystal nanomembrane to an
AlO-coated n-type-GaO epitaxial substrate. The resultant
heterojunction diodes exhibit remarkable performance metrics, including an
ideality factor of 1.23, a high rectification ratio of 8.04E9 at +/- 4V, and a
turn on voltage of 2.35 V. Furthermore, at +5 V, the diode displays a large
current density of 2500 A/cm along with a low ON resistance of 2
mcm.Comment: 14 pages, 5 figure

Intervenções de enfermagem nas complicações mais freqüentes durante a sessão de hemodiálise: revisão da literatura Intervenciones de enfermería en las complicaciones más frecuentes durante la sesión de hemodialisis: revisión de la literatura Nursing interventions for the most frequent complications during hemodialysis procedure: literature review
O procedimento hemodialítico tem complicações potenciais e o enfermeiro deve estar apto a intervir em tais complicações. Considerando este contexto, este artigo tem como objetivo descrever as complicações mais freqüentes relacionadas à hemodiálise e as intervenções de enfermagem a elas relacionadas. Esta revisão de literatura consiste em pesquisa as Bases de Dados, LILACS, BEDENF E MEDLINE, utilizando descritores pertinentes. Os resultados demonstraram que as complicações que ocorrem com maior freqüência são: hipotensão, hipertensão, cãibras musculares, náusea e vômito, cefaléia, dor torácica e lombar, prurido, febre e calafrios. Concluiu-se que o papel do enfermeiro é essencial para a monitorização, detecção e intervenção em tais complicações e que este é um diferencial para a obtenção de segurança e qualidade no procedimento hemodialítico. No entanto, existe a necessidade de realização de mais pesquisas na área de enfermagem para melhor definir a atuação do enfermeiro.<br>Lo procedimiento de hemodialisis tiene complicaciones potenciales y los enfermeros deben estar aptos a intervenir en ellos. Al considerar esto contexto, lo artículo objectiva describir las complicaciones más frecuentes relacionadas a la hemodialisis así como las intervenciones de enfermería. Esta revisión bibliografica ha consistido de busqueda a las basis de datos LILACS, DBENF y MEDLINE usandose descriptores pertinentes. Resultados han demonstrado que las mayores complicaciones son: hipotensión, hipertensión, distres musculares, nausea, vomitos, cefalea, dolor toracica y lumbar, prurido, fiebre y calafrios. Se ha concluido que el papel del enfermero es esencial para la monitorización, identificación y intervención en estas complicaciones y que esto papel tanbien es uno diferencial para obterse la calidad en lo procedimiento hemodialitico. Entremientes, hay una necessidad de realizarse más pesquisas en la area de enfermería para mejor definirse el papel de lo enfermero.<br>Hemodialysis procedure has potential complications and nurses must be able to intervent on them. Considering this context, this article aims to describe the most frequent hemodialysis-related complications as well as nursing-related interventions. This bibliographic review consists in LILACS, BDENF and MEDLINE search using pertinent descriptors. Results demonstrated that major complications are: hypotension, hypertension, cramps, nausea and vomiting, headache, chest and low back pain, scratching, fever and shriving. For these complications there are specific nursing interventions that can be delivered. It was concluded that nurse's role is essential for monitoring, identification, and intervention in such complications and that this role also is a differential to obtain quality in hemodialysis procedure. However, there is a need to perform more research in nursing area to better define the nurse's role
