Quantum well state of self-forming 3C-SiC inclusions in 4H SiC determined by ballistic electron emission microscopy

High-temperature-processing-induced double-stacking-fault 3C-SiC inclusions in 4H SiC were studied with ballistic electron emission microscopy in ultrahigh vacuum. Distinctive quantum well structures corresponding to individual inclusions were found and the quantum well two-dimensional conduction band minimum was determined to be approximately 0.53 ?? 0.06 eV below the conduction band minimum of bulk 4H SiC. Macroscopic diode I-V measurements indicate no significant evidence of metal/semiconductor interface state variation across the inclusions.open292

Awareness of high blood pressure status, treatment and control in a rural community in Edo state.

A cross-sectional study was carried out in Udo, a rural community in Ovia South-west LGA of Edo State to assess the level of awareness of high blood pressure status, treatment and control. Cluster sampling method was used to select participants and data collection was by researcher administered questionnaire. Blood pressure measurement was by standardized method. A total of 590 respondents with mean age 30.7 + 14.6 years participated in the study. The prevalence of hypertension was 20.2% using the WHO/ISH criteria of SBP >140 mmHg and/or DBP > 90 mmHg. Twenty two (18.5%) of the hypertensives were aware of their high blood pressure status. Awareness was higher in females, increased with age and decreased with higher educational status. Of those aware of their condition, 77.3% were on treatment and of these, 29.4% had adequate blood pressure control. This study has revealed a low level of awareness of high blood pressure status and control in this rural community. Therefore, there is urgent need for regular community-based hypertension screening programmes. Keywords: Awareness, Treatment, Control, High blood pressure.
