    The temperature dependence of morphology of InAs islands on Si grown through Stranski–Krastanow mode is investigated by atomic force microscopy. Formation of islands in the range of 15–50 nm is observed for depositions at various temperatures for the same monolayer coverage. Growth temperatures between 400 and 425 °C are found to yield dense ensembles of islands with uniform dimensional distributions. Found to exhibit long-term stability, these islands undergo morphological transformation when annealed at temperatures above 700 °C. Ostwald ripening occurs in these islands through an enhanced surface diffusion mechanism at high annealing temperatures. The results of annealing experiments indicate surface diffusion being the dominant mechanism responsible for morphological changes in these island structures rather than the heterointerface diffusion. © 1999 American Institute of Physics.

    Description / Table of Contents:
    Zusammenfassung Zähne spielen allgemein für die Identifikation von Toten eine wesentliche Rolle, was in einer Erfolgsrate von über 50% zum Ausdruck kommt. Deshalb setzt die Polizei auch in denjenigen Fällen, in denen Personen über lange Zeit hin nicht identifiziert werden konnten auf die Mithilfe der Zahnärzteschaft, indem sie Identifikationsfälle in zahnärztlichen Printmedien veröffentlicht. Um die Effektivität dieses Verfahrens zu untersuchen, wurden 177 Fälle aus den Jahren 1975 bis 1995 ausgewertet. Das Ergebnis ist ernüchternd. Nur drei Prozent dieser Fälle konnten aufgrund einer Reaktion auf eine solche Suchanzeige hin identifiziert werden. Um neue Kriterien für die Gestaltung von polizeilichen Suchanzeigen zu gewinnen, wurden deshalb 500 Zahnärzte zur bisherigen Präsentationsform der Suchanzeigen befragt. Die Auswertung dieser Befragung liefert die Grundlage für ein innovatives Konzept zur Gestaltung zukünftiger Suchanzeigen. Ein weiterer Schritt könnte in der Nutzung neuer Technologien wie dem Digitalen Röntgen oder der Datenübermittlung per Internet bestehen.
    Notes:
    Abstract Teeth are most important for the identification of unknown cadavers. The police publish difficult cases of unidentified bodies in dental print media. Using their records such as x-rays or documented dental work dentists can often recognize an unknown person and thus contribute to the identification. To evaluate the efficency of this procedure 177 cases published between 1975 and 1995 were examined. The result is unsatisfying. Only 3% of the examined cases could be identified due to a reaction to publishing in the dental print media. To improve the presentation of identification cases in the dental print media 500 dentists were asked to take part in a survey. According to these results a new concept of presentation sould be developed to improve the efficency of this odontoforensic method. New technological possibilities such as digital x-raying or online data transfer could open new ways for forensic identification.
