We report a study of the thermodynamic properties of indium clusters on a SiN x surface during the early stages of thin film growth using a sensitive nanocalorimetry technique. The measurements reveal the presence of abnormal discontinuities in the heat of melting below 100 ± C. These discontinuities, for which temperature separation corresponds to a(More)
The melting behavior of 0.1–10-nm-thick discontinuous indium films formed by evaporation on amorphous silicon nitride is investigated by an ultrasensitive thin-film scanning calorimetry technique. The films consist of ensembles of nanostructures for which the size dependence of the melting temperature and latent heat of fusion are determined. The(More)
We introduce a scanning calorimeter for use with a single solid or liquid sample with a volume down to a few nanoliters. Its use is demonstrated with the melting of 52 nL of indium, using heating rates from 100 to 1000 K/s. The heat of fusion was measured to within 5% of the bulk value, and the sensitivity of the measurement was Ϯ7 ␮W. The heat of(More)
The properties of nanosized bismuth particles are investigated using a nanocalorimetric technique. A brief description of the experimental method and data analysis procedures is reported. Bismuth nanoparticles are found to melt at a temperature below that of bulk material, but higher than expected using the standard model. Also included is the results of a(More)
This paper examines the mental health status of 945 Chinese older people who are in need of long term care services in Hong Kong. It was found that for those aged respondents who are already waiting for admission to infirmary, over 59.3% were already living in private aged homes, and only as few as 17.8% of these applicants were still living in their own(More)
Device junction temperature and other operating conditions are critical in determining the avalanche current capability and forward bias safe operating area for MOSFETs designed in different processes. P ower device performance continues to advance at a high rate. Each generation is also becoming more optimized and more specialized to particular application(More)
By using a Micro-Electro-Mechanical System (MEMS) device, the nanocalorimeter, it was possible to investigate the melting of isolated polyethylene (PE) single crystals grown from solution. Atomic force microscopy (AFM) was used to obtain an idea of the morphology and to determine thickness measurements. Transmission electron microscopy (TEM) was used to(More)
