Unlock exclusive artist performance data. In late , he returned to the CSIR. It was in Bristol in the period to that he started working on intercrystalline boundaries, together with Charles Frank.

Eventually their research led them to study epitaxy , and in they presented the fruits of their research in a series of scientific papers. The result was the Frank—Van der Merwe crystal growth model which carries both their names. From to he served as senior lecturer and Associate Professor in the physics department at the University of Pretoria.

During this period he again worked with a colleague from Bristol, Frank Nabarro who was then head of Physics at the University of the Witwatersrand , South Africa. In he took a sabbatical to the University of Virginia which led to a refinement of his initial model of thickening two-dimensional interfaces in The theory of epitaxy was a major focus of his career and he published many seminal papers, which resulted in him becoming known as the "Father of Epitaxy".

With the advance of the semiconductor industry from the s onward, epitaxy became extremely important as it depends on the growth of perfect single crystals for the manufacturing of transistors and IC circuits. An essential role in understanding how to grow such perfect crystals was provided by his theory. Van der Merwe's model of atomic forces paved the way for successful modelling of important physical phenomena in solids at the atomic scale.

He personally regarded his solution to a differential equation in his PhD thesis as one of his biggest achievements.

This was basically a soliton differential equation with an ingenious solution, the first ever analytical solution to a soliton problem. Solitons in solid state and other branches of physics became important for advanced applications in communication technology. During this period Van der Merwe was invited to present plenary talks at many international conferences, during which he made enduring friendships with several surface scientists including Ernst G.

In he spent a seven-month sabbatical at the University of Virginia where he collaborated with William A. Almost 30 years later, in he co-authored a paper with Jesser. In , he accepted the position of head of the physics department at the University of Pretoria. From this point on he regularly collaborated with Gary Shiflet of the University of Virginia.

Almost 20 years later, Shiflet and Van der Merwe co-authored papers on interphase boundaries. In a Symposium in honour of Van der Merwe was arranged by the American Society for Metals, Materials and Minerals to celebrate the 50th anniversary of his discovery of Interfacial Dislocations. In , just before leaving South Africa for Bristol, he married Minnie de Villiers and they had their honeymoon on the ship to the UK.

In late they returned to Pretoria, South Africa in time for the birth of their first child Pauline Willem was born in , Jan in and Anna was adopted in His son Jan died in , his daughter Pauline in and his wife in Van der Merwe died on his birthday, 28 February at the home of his son Willem.
