“…Once collected by the electrodes on the non-illuminated face, the charge carriers produce proportional pulses in voltage, which are measured by high-impedance MESFET amplifiers, mounted on the 4K stage in the He-3 cryostat. [6,7] The two-dimensional pattern of charge density is determined by measuring the charge collected by the small, circular electrode as a function of the position of the excitation point on the illuminated face. Because translation of the excitation point causes a corresponding translation of the charge density pattern, this procedure is equivalent to keeping the excitation point fixed, while moving the small, circular electrode to probe different regions of the charge density pattern.…”

Excited electrons in the conduction band of germanium collect into four energy minima, or valleys, in momentum space. These local minima have highly anisotropic mass tensors which cause the electrons to travel in directions which are oblique to an applied electric field at sub-Kelvin temperatures and low electric fields, in contrast to the more isotropic behavior of the holes. This experiment produces, for the first time, a full two-dimensional image of the oblique electron and hole propagation and the quantum transitions of electrons between valleys for electric fields oriented along the [0,0,1] direction. Charge carriers are excited with a focused laser pulse on one face of a germanium crystal and then drifted through the crystal by a uniform electric field of strength between 0.5 and 6 V/cm. The pattern of charge density arriving on the opposite face is used to reconstruct the trajectories of the carriers. Measurements of the two-dimensional pattern of charge density are compared in detail with Monte Carlo simulations developed for the Cryogenic Dark Matter Search (SuperCDMS) to model the transport of charge carriers in high-purity germanium detectors.

“…Thus, the processes of regulation of learning assume a challenging role in such a VET context: it represents a foundation in the collaborative locations in which the apprentices are embedded. Collaboration skills are central in VET (Lee et al 2015); being able to work with others and to learn with and from others is inescapable, whether in an office, in a plant or in the kitchen of a restaurant. Chefs, for instance, despite being often under stress and time pressure need to co-regulate each member's contribution, to ultimately ensure the group's performance.…”

“…Collaboration is considered as an essential learning outcome for the twenty-first century (Lee, Huh & Reigeluth, 2015) as it contributes to one's personal success in the collaborative learning context and workplace (Lai, DiCerbo & Foltz, 2017). Lai et al (2017) define collaboration as the process of interaction that requires individuals to work together toward a common goal.…”

Collaboration is now identified as an essential 21st century skills that make it become an important learning outcome. On the other hand, there is a growing demand to infuse engineering practices into science learning as it relies more on social involvement, such as collaboration, to solve problems. Thus research examining students' collaboration skills which emerge during activities involving engineering design is needed. Through observation method with rubric adapted from social skills of collaborative problem solving, emerging collaboration skills during collaborative engineering design processes are identified. The subject were 18 secondary students in 8th grade who were engaged in science lesson involving designing, constructing and testing analogical model of blocked artery and medical device to treat it. Varied level of participation, perspective taking and social regulation skills are evident throughout the lesson. Finding suggests that individual collaboration skills are dependent upon skills of collaborating partner
