    Notes: An enhanced analytical model is derived to calculate the junction depth and Hg interstitial profile during n-on-p junction formation in vacancy-doped HgCdTe. The enhanced model expands on a simpler model by accounting for the Hg interstitials in the p-type, vacancy-rich region. The model calculates junction depth during both the initial, reaction-limited regime of junction formation and the diffusion-limited regime. It also calculates junction depth under conditions when the abrupt junction approximation of the simpler model fails. The enhanced model can be used to determine the limits of the annealing conditions and times for which the junction depth calculated analytically is valid. The decay length of interstitials into the p-type region estimated analytically places an upper bound on the grid spacing needed to accurately resolve the junction in a numerical simulation. © 1998 American Institute of Physics.

    Description: People across Peru are vulnerable and exposed to a wide range of hazards, and studies demonstrate that these hazards are key drivers of migration in the country. Hydrometeorological hazards resulting in excessive amounts of water (in such forms as torrential rainfalls and floods) – or the lack thereof (in the form of, for example, drought or glacier retreat) – are particularly salient to migration. Climate change has intensified these hazards and will continue to do so, possibly resulting in new and unparalleled impacts on migration. IOM and the Potsdam Institute for Climate Impact Research have partnered to produce this report, which seeks to shed light on the available evidence on the environment, climate change and migration nexus in Peru. The study puts into perspective various climate risks and hazards that affect communities in the country’s main topographical zones: the coast, the highlands, and the rainforest or jungle. The report provides a systematic review of the complex interaction between climate and other factors driving migration in the country. It discusses the necessity to understand climate migration patterns and improve planning and policies in the short term to the mid-term, in view of several “no-analog threats” – that is, those with unprecedented, large impacts – that could occur towards the end of the century.
