During my research career, my interests were centred on the modeling of processes at interfaces. In the early 1960s, the field of surface science was in its infancy but due primarily to the growth of the semiconductor industry, over the following 40 years surface science developed into a major area of research located at the boundaries between physics, chemistry and engineering. The 60s heralded the paradigm shift in electronics from vacuum tube technology to solid state devices and there were many complex manufacturing problems that accompanied this innovation. Semiconductor devices (computer memory, lasers, photocells etc) are really quite uncomplicated and are simply layers of dissimilar materials grown sequentially, but the problem is the level of control must be accurate to the size of atoms. The condensation of atoms an molecules under this level of scrutiny is difficult to achieve but the reward is where we currently are in technology with computers, smartphones, GPSs and many more labour saving products.
