“…The EDMR signal is a reflection of the constituent singlet/triplet proportions within the ensemble of spin pairs. 157 By 1996, as little as 10 6 , 31 P donor spins had been observed, verifying the improvement to resonance detection sensitivity that EDMR could provide. 158 Although it was not until 2003 that Boehme and Lips demonstrated the imprint of coherent spin motion on a semiconductor current.…”

“…This model, known as the Kaplan, Solomon and Mott model, relies on the establishment of intermediate donor–defect or donor–acceptor pairs. 157,162 In this model, it is the relative orientation of the spin pairs that is important. The shorter lifetime of singlets results in a larger triplet population until resonance saturation increases the singlet population, thus reducing the recombination time and the steady state current.…”

“…Boehme defines SDR of charge carriers as ‘recombination through transitions whose probabilities are governed by spin selection rules’. 157 Spin dependent recombination involves the recombination of electron–holes pairs formed by photoexcitation or through doping to form a p–n junction. 140 Since charge carrier concentrations are affected by recombination, it can easily be measured as a change in conductivity of a device.…”

Literature review on: Quantum readout of spin resonance in a silicon transistor

Phosphorus donor spins in silicon are promising quantum bit (qubit) candidates. They have a natural confinement potential, long spin lifetimes and decades of use in the semiconductor fabrication industry. Readout of a single qubit is a necessary step to build a quantum computer, which could potentially solve particular problems exponentially faster than conventional computers. Electrically detected magnetic resonance has previously been used to measure the spin state of an ensemble of spins. In this literature review, the concept of a quantum computer is introduced before the potential of using electrically detected magnetic resonance to measure the spin state of a single donor spin qubit in a silicon transistor is discussed.

“…Hanel (1995) states that the dimensions of participation of cooperative members are: (1) member participation in the position of owner and (2) member participation in the position of user/customer. Other researchers who propose the dimensions of member participation are: participating in training (Tesfay and Tadele, 2013); participation in cooperative capital (Gemina et al ., 2020; Flecha and Ngai, 2014); service participation (Hannan, 2014); and participation in cooperative decision-making (Bhuyan, 2007; Unal et al ., 2009; Liang et al ., 2015).…”

PurposeThe purpose of this study is to look at the factors that influence the success of Indonesian cooperatives.Design/methodology/approachThis study employs a two-stage quantitative approach. Exploratory factor analysis (EFA) is used to determine the factors in the first step. The next step is to conduct a multivariate regression analysis to determine the impact of these factors on the cooperative success variable in Indonesia.FindingsThe components produced include Member Participation, Membership, Cooperative Governance Structure, Board of co-ops, Vertical Integration, Collective Action and Transaction Cost, according to the EFA results. A further study utilizing multiple regression techniques reveals that four elements, namely Member Participation, Board of Coops, Vertical Integration and Collective Action, have a major impact on the performance of Indonesian cooperatives.Research limitations/implicationsGeneralizations are impossible because of the small sample size and restricted responders. More studies are required, using a broader range of respondents and approaches.Practical implicationsThe results of the study contributed both to the stakeholders of cooperatives and to the development of cooperative science specifically in the context of Indonesian cooperatives. Cooperative stakeholders in Indonesia must realize that members are owners and customers of their cooperative. This awareness must continue to be echoed by cooperatives to its members in various ways, so that commitment arises to members to be willing to participate and cooperate. Awareness of members to participate and cooperate ultimately affects the sustainability of cooperative businesses and impacts improving members' welfare beds.Originality/valueThe study's novelty lies in a more comprehensive model of Indonesian cooperative success.Peer reviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/IJSE-02-2022-0078.

The purpose of this study was to improve the approach of environmental education in a secondary school in Pinar del Río, Cuba. This material was created using a) literature on the theoretical−empirical background of environmental education focused on Zoology and b) a study of student perceptions of the environment using surveys and interviews. Deficiencies noted in the literature and student knowledge guided the design of a multimedia program to teach Zoology to high school students with a focus on an integrated environmental approach. The proposed program includes specialized videos and texts about both global and local fauna. The videos and activities were designed to familiarize students with the fauna and the measures that they should take to protect and help preserve the life of animals and their environments.
