“During annealing, the morphologies of thin InGaN epilayers have been observed to change from a terraced structure to a network of interlinking InGaN strips separated by troughs. This change in morphology may contribute to high efficiencies

in some GaN-based light emitting diodes (LEDs) if the InGaN is exposed to elevated temperatures without a protective GaN capping layer. Here, we investigate the changes in morphology which occur when InGaN epilayers are annealed at their

growth temperature under NH(3), N(2), and SBI-0206965 a small H(2) flux. We observe that while the layers initially roughen, more extended anneals lead to the surface becoming smooth and terraced once again. Power spectral density analysis of atomic force microscopy data is used to show that the dominant mechanism for roughening is loss of material from pre-existing pits, while the dominant smoothening mechanism is surface diffusion. This mechanistic analysis may be relevant to the growth of InGaN quantum wells in LED structures.”
“Objective For families with dependent children, the situational crisis of a cancer diagnosis may compound the developmental task of parenting. This study aimed to explore the impact of breast cancer on Korean mothers and their VX-770 mouse children following diagnosis. Methods Korean women diagnosed with breast cancer at 50 years or younger more than a year ago were recruited by posting announcements at a breast cancer clinic and through referrals and snowball sampling. A one-time in-depth interview ranging from 60 to 90?min was conducted and data were transcribed verbatim for content analysis. Results Five

themes emerged from the data: (1) The delicate balance of being able to focus on self, which also was a conflicting factor in their relationship with children; (2) The continuing challenge of taking care of children, which was closely linked to supports, health condition, and cultural notions of parenting and lingering stigma; (3) The importance of informing children in a timely manner; (4) An overall shift in attitudes towards raising children as independent beings; and (5) Relinquishing and re-envisioning the future for their children and themselves. Conclusions Breast cancer brings new challenges in motherchild relationships with culturally framed issues. Findings can guide healthcare providers in giving relevant anticipatory guidance for women diagnosed with breast cancer and in considering family-focused psychosocial and behavioral interventions for families with breast cancer.
